Love these sandals. I have been looking for sandals that have good arch support, are durable for travel, outdoor activities but still fashionable! These sandals meet all requirements! I am anywhere from a size 8-9 in shoes . Normally I am an 8.5 the size 8 fits me perfectly. Only issue I have found is that these seem a little narrower but not too narrow that my foot doesn't fit. It slight hangs over the edge but not a big deal breaker for me! LOVE THESE and highly recommend trying them!
