It is very likely, and almost all Ski~Mojo users with knee issues agree, that you will feel a real difference.
With the recommended settings, Ski~Mojo eases the load on your knees by about one third. This can immediately, profoundly and lastingly reduce the pain you are used to, and in many cases, eliminate it altogether. By allowing you to put more pressure on your skis, it also improves control of your turns and helps prevent future injuries.
The Ski~Mojo works like a shock absorber, softening the impacts and vibrations from the slope. As a result, your joints experience far less strain from these repeated shocks, which can reduce or even completely remove inflammation.
For further details, take a look at this article: What effectiveness on my knee, back, and hip problems?
Absolutely! Skiing sends shocks and vibrations through the whole body, reaching the pelvis and lower back. By acting as a shock absorber and helping you maintain the ideal skiing stance, the Ski~Mojo reduces these vibrations and lessens the strain they place on your back and hips.
Just like the electric-assist bicycle, the Ski~Mojo has also won over many skiers who have no physical issues at all.
Even athletic, young skiers find that the Ski~Mojo adds real value on the slopes. By reducing muscle fatigue and boosting endurance, it lets you enjoy every ski day for longer. You can link more runs, keep precision in technical movements, and still feel fresh at the end of the day.
The Ski~Mojo is far more than a tool for relief or compensation. It acts as a true power amplifier, absorbing shocks and making skiing smoother, more comfortable, more precise in turns, and more powerful. Many strong skiers who try it discover that they enjoy the sport even more, pushing their limits while limiting the risks of fatigue or injury from overexertion.
Walking is a movement that is hard to reproduce with a purely mechanical system. The Ski~Mojo was created for skiing (as its name suggests), a motion that is much simpler, mainly involving bending the knees while the feet stay on the ground. Walking, on the other hand, is a very different process. When the Ski~Mojo is activated, walking becomes more difficult, but you can easily switch it off to regain full freedom of movement.
The Ski~Mojo also needs a solid anchoring point on a boot, which is provided by ski or snowboard boots. However, wearing these boots for everyday walking is not comfortable.
Many Ski~Mojo enthusiasts also use it for ski touring, but only for the descent! Indeed, while climbing, it won’t hinder you, but it won’t help you either.
For the ascent, you have two options:
In both cases, the Ski~Mojo will bring you a lot of enjoyment and comfort during the descent. To convince yourself or for further explanation, you can read this article: Ski~Mojo and Ski Touring: it’s possible!
Yes, the Ski~Mojo can be used for telemark skiing. By reducing the weight felt by your legs, the Ski~Mojo will significantly increase the endurance of your quadriceps. You will be able to make many turns before taking a break.
However, a few technical aspects must be taken into consideration:
The activation and deactivation of the Ski~Mojo are two terms that refer to turning on or off its support mechanism (purely mechanical, as no electrical power source is required). Here is a detailed explanation of these two modes of operation:
After a few runs, activating and deactivating your Ski~Mojo becomes second nature.
Most of the time, the answer is no, and when there is an effect, it is usually a positive one.
The Ski~Mojo helps you find an ideal stance thanks to the proprioceptive feedback of its harness. It also enhances the edge grip of your skis on hard snow. All skiers, including professionals such as instructors and ski patrol members, perceive its impact as beneficial.
Only those accustomed to lifting a ski to initiate a turn (a method known as the “stem”) may feel slight discomfort at first, as Ski~Mojo keeps the skis firmly on the snow to improve grip.
Above all, the reduction of fatigue allows you to focus on your technique, ski more safely, and extend your time on the slopes.
If you wonder how long it takes to get used to the Ski~Mojo, our satisfaction survey is reassuring: 87% of users adapted in less than half a day. If, after a full day, you are still not comfortable, the settings probably need adjustment. Contact us and we will gladly help.

The Ski~Mojo supports about one third of your body weight. This means your legs have 15 to 30 kilograms less to carry, which calls for a short adjustment period that rarely lasts beyond two or three runs.
For the best experience, we recommend testing the Ski~Mojo first on long, gentle slopes rather than starting with demanding terrain. The first turns may feel unusual, but by the end of your first run you will already be more at ease. After two or three runs, most skiers regain their balance completely.
If you wonder how long it takes to get used to Ski~Mojo, our satisfaction survey is reassuring: 87% of users became comfortable in less than half a day. If, after a full day on the slopes, you still do not feel at ease, the settings may not be correct. Contact us and we will gladly help you fine-tune them.

The Ski~Mojo is suitable for all adult sizes (height > 1.55m / 5’1″) and all body types. The telescopic rods adjust based on the length of the tibias and femurs. The harness and neoprene have adjustable Velcro straps, and unlike a brace or orthosis, these Velcro straps do not need to be tightened too much.
The only choice you need to make at the time of purchase is the spring strength. There are three different springs. So, choose your Ski~Mojo based solely on your weight.
As you can see, there are overlap zones, and some people may have the option of choosing between two models. To make your selection, choose the model that allows you to be as far away as possible from a minimum or maximum setting. To help you in your choice, you can refer to the table below.
No, there is no maximum weight beyond which you cannot use the Ski~Mojo. However, there is a maximum level of assistance.
The Ski~Mojo’s assistance is adjustable to the nearest kilogram to support 1/3 of your body weight (for standard settings as recommended in the User Manual).
Beyond a weight of 127 kg (280 lbs), you will have reached the maximum level of assistance. For example, if you weigh 140 kg (308 lbs), the Ski~Mojo will only support 42 kg (92 lbs), which is no longer 1/3 of your weight but still provides significant assistance.
Additionally, the Ski~Mojo comes with a neoprene sleeve that allows for a maximum thigh circumference of 60 cm. If this size is too small, you have two options:
Yes. If your doctor has prescribed a knee brace or support for laxity, you should absolutely continue using it. The Ski~Mojo fits over the brace and reduces the pressure on your knees, greatly easing pain and protecting the cartilage.
The two devices complement each other perfectly: the brace keeps your knee properly aligned, while the Ski~Mojo lifts about one third of your body weight off the joint and absorbs shocks and vibrations — tasks the brace cannot perform.
Unlike a brace or support, the Ski~Mojo is not a compressive system. Its Velcro straps do not need to be overtightened, so once in place it quickly becomes unnoticeable.
The answer is no. The Ski~Mojo does not cause muscle loss, because it does not eliminate muscular work, it simply redistributes it. By taking on part of your body weight, it lightens the load on the quadriceps, reducing the effort needed for each movement. The muscles still contract and engage in the same way, just with less intensity. This allows you to sustain effort longer and maintain endurance without overloading your legs.
In other words, the Ski~Mojo reduces strain without stopping your muscles from working. You avoid the quick build-up of fatigue while keeping the same type of muscle activation. Plus, because you can ski longer and with greater intensity, your muscles remain stimulated and active, helping to prevent any loss of strength.
When muscle activation is excessive, lactic acid accumulates faster than the body can clear it. This leads to burning sensations, stiffness, and soreness after skiing. Skiing alone can overwork the quadriceps, making it hard to link turns or extend your day, even when the rest of your body is still fresh. The Ski~Mojo helps balance that effort so you can enjoy longer, smoother runs.
In general, a fall with the Ski~Mojo has similar consequences to a fall without it. Often, the Ski~Mojo provides extra protection by dispersing the impact across a larger area. Likewise, if you are struck from the side by another skier, the device can absorb a significant portion of the shock instead of your legs.
Nevertheless, skiing remains an inherently risky sport. As with skis, poles or a backpack, any piece of equipment can sometimes cause injury, and the Ski~Mojo is no exception. This is particularly true in slow sideways falls. The neoprene sleeve helps to lessen bruising, though the risk cannot be completely eliminated, especially if the adjustment is incorrect.
As with your ski bindings, proper fitting of the Ski~Mojo is essential. Be sure to follow the guidance in the User Guide provided with your device.
The first set up (including adjustments to your body shape) only needs to be done once and will take just a few minutes. However, it is recommended to do it indoors before heading to the slopes. The User Manual will guide you step by step through this initial process. A detailed video is also available here:
For daily use of the Ski~Mojo, putting it on only takes one or two minutes when getting dressed. If you wear it under your pants (as 50% of users do), simply put it on before putting on your pants and boots. You will then just need to connect the Ski~Mojo to your boots.
The only tool needed to adjust the Ski~Mojo is the Allen key (also known as a hex key) provided. It will no longer be needed afterwards, unless you need to modify the settings.
A drill and a 4 mm bit will be necessary if you install the permanent connectors yourself on your alpine or touring ski boots (but if you go to a store, the retailer will do this for you).
The Ski~Mojo fits almost all alpine ski boots or touring ski boots. The attachment to the boot is done using “boot connectors.” The Ski~Mojo comes with two pairs of connectors:
Snowboarders will need specific connectors, which are available for purchase on our website (under the Shop/Accessories section) or from most of our retailers.
The total weight of the Ski~Mojo is 1.6 kg (3.5 lb).
But, like the battery of an electric-assist bicycle that allows you to go faster and farther, the Ski~Mojo gives you a feeling of lightness by supporting one-third of your own weight. These 1.6 kg (3.5 lb) therefore reduce the perceived weight on your legs by 20 to 40 kg (44 to 88 lb). You will ski feeling much lighter.
Both options are possible:
50% of users wear their Ski~Mojo completely invisibly under their ski pants (any ski pants that are not tight or form-fitting are suitable). The other users wear their Ski~Mojo over their pants, visibly. However, be aware that wearing your Ski~Mojo over your ski pants can carry certain risks:
Additionally, if snow gets into the mechanism (in the event of a fall, for example) and compacts or freezes, your Ski~Mojo may stop functioning properly until the snow melts.
It’s very simple, including for women! Detach the harness at the front clip, disconnect the upper rods from the harness (at the two side clips of the harness), and lower the harness. Once finished, do the reverse procedure to put the Ski~Mojo back on. This operation takes no more than 15 seconds.
If you need further explanations, watch this video which will allow you to understand everything:
Not at all! It’s just surprising the first time, but it poses no problem.
You can also keep the Ski~Mojo activated until you reach the top. Having the Ski~Mojo activated will help you stand up to exit the chairlift.
The Ski~Mojo should be activated when you are ready to ski with your skis on. We recommend deactivating your Ski~Mojo in all other situations, especially:
On a drag lift, you can keep your Ski~Mojo activated.
Additionally, for the Ski~Mojo to function properly, it must be installed on both legs. This is why, when you purchase a Ski~Mojo, it comes with both a right and a left leg.
It is also recommended not to ski with the Ski~Mojo activated on just one side, or worse, to use only one of the two legs provided in the Ski~Mojo kit. Unlike a brace or orthosis, the Ski~Mojo relieves weight on both legs, which creates its beneficial effects. Using the Ski~Mojo on just one side will create an imbalance and shift all your body weight onto the other leg. Just like you wouldn’t use an electric bike with only one pedal motorized, don’t use the Ski~Mojo on just one leg.
None, except for paying special attention when you take off your Ski~Mojo: make sure to dry it before storing it and fold the Velcro straps back on themselves to extend their lifespan.
However, the Ski~Mojo has some wear parts, and we recommend sending it to us for servicing after 70 to 90 days of use.
The Ski~Mojo is an exoskeleton. Just as your skeleton is connected to the ground through your feet, the exoskeleton needs to be connected to the ground (via ski or snowboard boots). If your Ski~Mojo is not connected to your ski or snowboard boots, it will slide down. So, this can’t really be considered a flaw since its exoskeleton design requires attachment to the boots.
This is why we have developed specific suspenders for those who need to wear their Ski~Mojo without having their boots on. You can find them in our online shop (under accessories) or at our retailers.
If your Ski~Mojo slips donwn while connected to your ski (or snowboard) boots, it is probably due to an adjustment issue. In this case, feel free to contact us. We will ask you for a photo that meets these 4 criteria:
This photo will allow us to diagnose your settings and quickly provide you with the right advice.
To understand this sometimes unpleasant but very easy-to-correct sensation, you need to take a brief look at mechanics… and be willing to question your stance.
When you adopt a centered position (left image), the Ski~Mojo works by exerting an upward vertical force. This force relieves your legs and knees, while generating a downward reaction that ensures good ski grip and better control of your turns.
However, when you lean into a backward position (right image), the forces from the Ski~Mojo are no longer vertical. They push your hips backward and your skis forward. You may feel as if the Ski~Mojo is “pulling” you backward, while in fact it merely emphasizes an already existing poor posture.
By making you aware of an imbalance you may not have noticed, the Ski~Mojo encourages you to naturally correct your stance. Very quickly, you will regain a more academic, centered position on your skis, for greater comfort and efficiency.
All components of the Ski~Mojo are detachable and replaceable by any of our retailers. The repair or replacement of the broken part is covered during the warranty period, provided you can demonstrate that your Ski~Mojo is still under warranty (keep your purchase receipt).
If you experience any problems, simply contact us by email or phone and we will help you get back on the slopes with your Ski~Mojo as quickly as possible.
We also offer a remote repair service. Check out the Shop / Services section.
To minimize the risk of damage, we recommend following our expert tips:
Your Ski-~Mojo comes with a 24-month warranty. Wear parts (such as the cable, neoprene sleeves or ski-boot connectors) are not included, unless they show abnormal wear. Keep your proof of purchase (a photo on your phone works well) so you can confirm your purchase date if you visit a Ski~Mojo retailer at a resort.
After registering your warranty on our website, you can extend it up to 48 months if you wish.
Most importantly, our goal is to see every skier enjoy Ski~Mojo to the fullest. We are committed to assisting anyone who experiences a problem caused by a manufacturing defect, even after the warranty has expired.
YES. In this case, you will use the temporary connectors provided with your Ski~Mojo.
You will need to buy a new pair of permanent connectors (just a few dozen euros) and fit them to your new ski boots. If you prefer, you can try removing the connectors from your old ski boots, although this is often tricky. A good tip is to gently heat the metal part with a hair dryer: the glue on the screw will soften, making it easier to remove.
Since the winter of 2021, the Ski~Mojo has been proudly manufactured in France, in two workshops located in the Rhône-Alpes region. Before that, production took place in the United Kingdom.
For more details about how the Ski~Mojo is made, visit this page:
The Ski~Mojo is equipment designed to make skiing or snowboarding easier, just as an electric motor makes cycling more accessible.
For this reason, the Ski~Mojo is not classified as a medical device and, in most countries, is not covered by health insurance. This does not prevent some doctors from recommending it to patients, much like they might advise using an electric-assist bicycle in other contexts.
There may be exceptions in certain countries or for specific professionals. If in doubt, check with your insurance provider.
