Not used yet. Although I like their quality. The velcro is rigid and has a double closure. The fleece is fluffy and the inside of the flared boot is made of memory foam. I have Ventech boots to match. I will say that the material on the outside of bell boots is difficult to clean. It is water resistant but has a texture that dirt can get stuck in. There's nothing a scrub can't fix, and they're actually WHITE so I doubt they'll ever stay clean. But only on the head.
