My husband has flat feet and he wears out a pair of shoes or boots in no time. We've tried a lot of quality brand shoes but he still complains about shoes being uncomfortable. He dislikes the foam insoles, and the memory foam insoles that form to your feet always was up on the insides of the shoe from sliding, he can't use the ones that are sticky on bottom to hold them in place cause after few days he's ripped them so I was skeptical here...but glad I chanced it. They are great he actually called me that afternoon and said order a few more pair for his other shoes! Compliments on anything from him means alot so I know they're great.
He wears size 13 shoe in a wide and these were long enough and they covered entire area in the shoe. He said they didn't slide when he put on his shoes and hadn't made his feet sweet. So extra support for his flat feet
