I had a problem with my toe, and someone recommended issue to me I purchased it and I love it, the only problem with it is that it should have some type of permanent tab to attach the tongue to the laces coulis the tongue is relatively short.  I fixed it by punching holes in the tongue and threading the laces to it and throw it which solves the problem.  But as far as the ability to walk it certainly has helped me and I walk in them every day couple of miles recommend them to anybody
