I have bought these shoes several times and am very happy with them. What happened? My husband has diabetes and severe pain in his legs. This shoe has worked great for him in the past but this latest purchase is a total disappointment. The shoes, bought in August, had a weird chemical smell but he thought it would dissipate. it only intensified and the soles completely detached from the shoes. Needless to say, he can't wear them. What the hell has changed? Offerer?
