Very supportive and comfortable.Comfortable.The left foot is small?These shoes were not perfect, although I have never found better...so for that, I am giving them 5 stars. I have flat feet and therefore walk with overpronation. Walking/standing for long hours at work was killing my feet. These shoes arrived and the sandal straps were way too tight- I pulled them onto my feet and wore them around for a few hours... Breaking in the straps was actually quite painful on the tops of my feet. I ordered an 8 when I'm typically a 7.5 because I had read reviews saying they ran small- I'm very glad I ordered an 8! They are not big on me at all. So order at least a half size up! Other than that, these shoes have saved my feet! They are comfortable, I can wear them for 12+ hours at work, the cork foot bed is nice for absorption of any sweat my feet secrete throughout the day... Wonderful!Love these SOLE sandals! I had plantar fasciitis and was told I needed better arch support in my flip flops. Living in Hawaii, I wear flip flops ALL the time. Well, I got a pair of these and within a month, my plantar fasciitis was gone! It's never come back. I still have a few cute, flat sandals, but if I'm going to be on my feet for any length of time. These are my go-to pair. I actually have this style in 3 different colors, but these are my favorite. They've stood up to the wear and tear the best.I have high arches and need a sandal which hugs my arch. This sandal does that. I would suggest getting fitted for them at a running store prior to purchasing so you get the proper size. Once you know your size can then order on line. Very comfortable for all day wear and not affected by water at all.I like these. I am a distance runner who has dealt with plantar fasciitis in the past and find that that the supportive arch and firm cork bed of this sandal really works for me. The thong that sits between the toes felt a little rough initially on my admittedly sensitive skin, but it broke in quickly.I have worn SOLE flip-flops for a few years now. I wear them when I have heavy walking to do, i walked all over Paris in them two years ago. There is nothing more supportive in any shoe, not just the flip-flop category. As instructed by the manufacturer, they are easy to scrub clean too!
