i Walk 2.0 size requirements – will the iWALK3.0 fit me? If you’re built like 95% of the human population, the answer is YES!  But wait… it’s not quite that easy.

What matters most is leg length. But since most people don’t know their leg length, we use height as a starting point, because everyone knows their height. And unless you are toward the shorter or taller end of the spectrum, height works fine. Which means, if you’re between 5’1” and 6’1” read no further, iWALK3.0 will fit you. For everyone else, check the chart below:

iWALK3.0 SIZE CHART – based on user’s height

If your height is in the yellow or red zones, there’s a 5% chance that iWALK3.0 will not fit you. You need to consult the user’s leg length chart below to confirm your measurements are within the size range of iWALK3.0

Measure both upper and lower leg as shown. If you fall within the ranges shown, iWALK3.0 will fit you, no matter what your height is.

FAQ: Why do UPPER and LOWER leg lengths matter?

Not all legs are created equal. Two people with equal overall leg length may have different upper and lower leg proportions (see diagram below). The iWALK3.0 crutch accommodates this by having both upper and lower leg length adjustments, but there are limits. To be certain that your leg proportions are within the limits of the adjustment range of the iWALK3.0, check the chart seen above. If you are, the iWALK3.0 will fit you.

If you weigh over 275 pounds (125 kg) or are significantly overweight, iWALK 3.0 is not a suitable option for you.

FAQ: Why does it matter if I’m significantly overweight?

Body mass can play a significant role in the way the crutch functions. The iWALK crutch needs to become an integral part of your leg in order to function at maximum efficiency. If your leg moves, the crutch moves accordingly. Any excess movement makes the crutch harder to use and less efficient. And, the fact is that the more body fat you have, the more “compressible” flesh you have, which allows more movement of the crutch. The less movement, the better – you want the crutch rock solid beneath you. Also, being overweight introduces different thigh shapes that can exceed the adjustment limits of the iWALK that relate to where the foot will be positioned.

So if you’re overweight, does that mean you can’t use it? Not necessarily- we’ve seen people of all shapes and sizes use the crutch successfully. Just be aware that people with high body mass indexes may have more difficulty, especially initially, and should set realistic expectations before purchasing the iWALK.

Potential Knee Comfort Issues

In rare instances the iWALK3.0 can cause localized soreness in the tibial tuberocity, which is the area of the shin directly below the knee.

For most people, the transition from the knee to the shin (tibia) is fairly straight, but some people have a pronounced bump. In extreme cases, the size of this protrusion is more than the standard foam padding on the iWALK3.0 can support, which can result in a localized painful “hot spot”.

Fortunately, there’s an easy solution – just augment the existing foam near the front of the crutch to accommodate the condition. You can purchase a replacement pad from us and simply install it on top of the existing pad, or you can also try some other readily available remedies, such as a folded hand towel, inexpensive gardening knee pads found at home improvement stores, etc. To gain a better understanding of the situation and the solution, see our diagrams below.

We could simply use a thicker pad to accommodate everyone, but we don’t – and here’s why. The connection between the leg and the crutch is crucial for feel and control. Basically, you want the iWALK crutch to be an integral part of your leg. Having no padding would be the ideal, but it would be too uncomfortable. So we intentionally use the minimum amount of padding to provide the best compromise between comfort and control.
