Very comfy-once you get them on. It really does feel like you're on a yoga mat, but that also gives you a slightly slippery situation if it's warm out. Also, the way the slip in fabric is, great quality and super soft and silky, but a pain in the butt to get your feet into. I've never had sandles like this before so it's a change for me, and I like them very much. I just didn't realize I wouldn't be able to essentially step into them and head out.
