When they first arrived and I tried these on, I thought the fit was great but after wearing a few times I feel like the toe portion of the shoe has stretched out.  The thick back heal portion is too stiff and rigid and rubs against the upper portion of the heel.  They're very uncomfortable and I doubt that I can wear them any longer. I do not wear my fitness shoes back and forth to class or outside of class.  I have worn them only in a one hour strength class approximately six times.  They've become downright painful!  Unfortunately, I've waited over 30 days and I'm not sure if there's anything that can be done.
