I hate these slippers with a vengeance. The little massage nubs have torn the bottoms of my feet to literal shreds. I took to wearing them with socks, but they have also frayed many of my socks. The little massage nubs break off and fall all over the house, and in general, I cannot wear them for even a few minutes without throwing them off because they feel as though they are pinching the bottom of my feet. They are so painful that I need to keep an additional pair of slippers for my bathroom because I can't possibly wear socks 24-7. The only reason I lived through the discomfort and tried to wear these slippers with socks was because I had plantar for a few months and these slippers were at least not exacerbating it, but the bottoms of my feet just can't take it anymore. I have no idea why the nubs are this sharp and this painful, but they are really not worth the trouble. Avoid these slippers if you have even slightly human-like normal feet and don't enjoy pain.
