text: Another reviewer said they're bent backward. She thought it might have been from heat during shipping. I don't think so bc mine are bent on a curve too. They're not comfortable but not painful either. The velvet feels nice on the bottom of my feet (like slippers) but the cheap plastic makes them a little clunky & stiff. The bend didn't help that. I'm keeping them since they were only 7 bucks & they're good to just have around; which shows they're not so bad that I'll return them. Good spares, I guess, but they are definitely cheaply made & why they're so cheap in price.
