This is the most comfortable slide I've ever had. It has a nice arch support - good for my plantar fasciitis. Sizing is tricky though. I wear a size 8-1/2. I purchased size 8. It fits comfortably, but there is no extra room. Another consideration is the rubber material. I'm wearing with socks now, and it's a bit tricky to get my foot in. Will wear without socks soon.
