This is an excellent product which clearly deserves the glowing reviews that others have given. With a broken ankle which could bear no weight I was struggling with crutches, but with the iwalk 2.0 I am able to get around with far more confidence. There Is, however, one issue that has bothered me. No matter how carefully I tighten the straps they quickly loosen. The crutch the drops when I lift my leg and if I am not careful the foot drags when I move forward, causing me to stumble. As the Vibram sole gives excellent grip this is a problem on all surfaces and even slight contact can pitch me forward. Nevertheless, this issue does not change my view that the iwalk 2.0 is an excellent product.
