I love these acorn slippers. I am on my third pair in six years, but I'm tough on them (dashing outside to get this or that, I must fess up). They are adjustable with the flap across and if it's really cold, adding socks will add extra warmth. The bottom is a scuff pad, adding to the durability so it's not fabric all the way around, and they're washable. Acorn does make good slippers but shop around, because they can be a bit pricey. I was glad to find this style on Amazon.
