I live on a creek with fabulous hiking trails "on the other side". I usually wear water sandals across then change to hiking shoes. I've tried numerous combinations. I have short wide feet and had little luck finding anything comfortable. My DIL had a pair of these that I tried on. I was suprised they fit, I mean they're little kid shoes OK big kid shoes. They not only fit I hiked up the mountain and down, a three hour tough hike and forgot to change into my hiking shoes. These were great, creek water came and went, no rubbing, very stable. I can't say enough nice things about these sandals. I normally wear a womens 8.5W or mens 7 now a big kids 6. All depending on the shoe of course. I wish they sized shoes by the insole length and width as opposed to an arbitrary number that may or not be the same from shoe to shoe.
