These are basic moccasin type slippers. I would not recommend wearing them in warm weather because the fleece inside is very thick. Since it is man made fleece it really makes your feet sweat. The outside is man made suede like material. They are not well made like uggs but then again they are very inexpensive and a pretty good buy for the money. I can tell I will get about one year out of them. I would not wash these as they will likely fall apart.
