These are my first rainbows & I'm glad I finally caved and bought them. Haven't worn them outside the house yet but I've been trying to break them in- so far not as painful as other reviews have warned. You can tell they are of a much higher quality than other flip flops & will probably be worth their price in the long run. I'm a size 8-8.5 and the women's L fits perfectly, although they are a bit narrow- if my feet were much wider I would have had to go with the men's version.
