Comfy but cheaply made. I bought these for the price and expected them to be not the best quality but they are even less than I expected. Please also note that they run small. I got a 10-11 since I wear 11 shoe and Amazon recommended this size. I think a size larger would have been better. Not worth returning though. I’ll just wear them this winter if they last that long and get a better brand next time.
