If you’re a fan of wool, these slippers (or house-shoes) will be your feet’s best friend! These have never been worn outside, but certainly could be given they have a decent textured rubber sole. However, they are just felted wool upper, so not a lot of structure for lengthy walks. Barely worn… there is a small heel cup. As felted wool does, some fibers work themselves loose. It’s not an issue of quality, rather it’s eco-nature! Cozy warm for coffee mornings!
