At first everything about these shoes was great. I have flat feet which are a bit wide and I'm heavy so discovering and reading about diabetic shoes and how they are a bit wide was great to find something that fits and is comfortable all day. And it was great. For four months. Then I started sorting out the inner lining of the boot. Within a month I was completely done. I have included photos of how the interior looks now less than 6 months after purchase and this started two months ago. I'm sure the solution would be to buy insoles, but I don't know how that would change the internal fit of the shoe. However, I don't think this should happen after 4-5 months of wearing. Will I buy them again? I could try again and add inserts, but I don't have to.
