I don't see how these would be beneficial for anything. Yes, they're light-weight. But, they're extremely cheap. The materials are what I'd expect if you sprayed expandable foam into a mold. I don't see how these can possibly have any positive reviews. The shoe portion itself is the correct size for my foot, but there is SO much extra room in there, that it just looks funny wearing them. They gave my wife a good laugh, now returning.
