So comfortable. I look forward to kicking off the dress shoes and socks everyday and putting my feet in fur heaven. They are well built, a little heavier than you would expect, but I believe that is due to the build quality. One guy complained about the fur clumping up. Mine did too, under my toes. I just reached in each one and scarped it around with my fingers and viola, back to even distribution. Did that about a month after I got them and haven't had to since. But I will if needed, cause I love these puppies!
