An Acorn original all new and improved this year. Double layer polyester fleece is now lined for more shape and improved comfort fit. New loftier Acorn memory foam midsole over their new comfort cushion layer of featherweight EVA guarantees relaxation therapy for feet. Durable suede leather side wall and a waterproof outsole with skid resistant tread for those jaunts out to the mailbox or to chase the dog. If you have wide feet this slipper will fit you nicely as it has a nice gentle stretch to it. Wear with or without socks.
