I bought these slippers to use as slippers as I was looking for something that didn't get my feet too hot and also offered a bit more support to mine Feet as I have some problems with bunions and high arches. The bumps feel a bit strange barefoot, but you get used to them quickly and actually feel quite comfortable. I usually wear size 10 1/2 or extra wide shoes. For me, a size 12 fits these shoes the best so they don't sag and stay comfortable in the toe box.
