I always prefer breathable slippers. My favorite sneakers so far have been the Sketchers Slip-Ons. I have to admit that the Sketchers are a higher quality shoe, but when it comes to comfort, the Outdowals can't be beat for comfort. The material is soft and they are very comfortable to wear without socks. Shortly after receiving these, I ordered two more pairs. I don't expect them to last as long as sketchers, but at a third of the price of sketchers, they're worth it.
