the memory foam compresses with wear but take them off and they puff right back up (except the popped section) overall great price, decent value, poor choice of material for underside. The clasp is very small which makes it a bit difficult to put on. Wasnt really expecting much, especially for the price I paid back then, but thought they were worth a shot. Best Buy! I am size 7 1/2 and the slippers fit size 7 to 8. DO NOT BUT FROM THIS SELLER. This "fur" has a slight shinyness to it. But this is a good thing because that is how the product stays sturdy without the need for screws and other complicated assembly steps. I also didnt know how my baby would be delivered. could cause an accident.
