I bought a pair of men's gdefy shoes. They felt weird at first but I thought I would get used to them. They always made me feel like I was wearing high heels and after a month I noticed my lower back was kind of sore. I quit wearing them to see if that made a difference and within a week I felt fine again. Good for somebody else maybe but not for me. I am past the 30 day return policy so I guess I'm stuck with them. Maybe I will just give them to goodwill. Thanks anyway gdefy.
