I love these shoes. BUT. I first bought a pair of these shoes at a local shoe store. I loved the fit and feel so much that I bought a second pair from Amazon. The shoes are very light and true to size. However, after wearing them four times for indoor racquet sports, I noticed that the bottom of the shoe wears out very quickly. to the point where the "springs" on the underside would wear out completely if I tightened them four or five more times. I'm not sure what to do. I love shoes but feel like I'm not getting my money's worth.
