I really wanted to love these shoes, and I did for a few months. But last month one of the bottom treads came loose and now it's just kind of hanging there. I can still wear them but I'd be hesitant to wear them for more than work. Pretty disappointed that they didn't even last 3 months before starting to fall apart. I bought them specifically for working out but I'm hesitant to get on the treadmill with them now as I'm afraid they might catch and trip me!
