Gave me a blister only on my right heel but after it healed and I wore them again it hasn't happened again...
they do fit smaller than expected, but I don't return things  But after a while they seem to adjust nicely to my feet. They look amazing with casual shorts and a tee. I think these shoes pull it together better than flip flops or flat sneakers. Adds a little more boho personality. I like the design of the fabric. Would recommend, definitely:)
