At first I was a bit wary of them because of the high arch and tight straps which sit lower than my normal flip flops, but these grew on me. They're heavier than I expected, which probably accounts for the lower strap line, but they're not uncomfortably low or heavy, so neither is a con. The leather is soft and forms quickly to your foot. I wear an 8/8.5 and originally ordered an 8, but they were too small so I got a 9. They fit great with a little room around my feet. My flat feet are happy in these arched sandals and I wear them nearly every day now. Insta-fav!

I was just diagnosed with Posterior Tibialis Dysfunction due to the high arches in my feet. These flip flips are so comfortable and have the arch support I need. I want a second pair of Chacos very soon. These shoes very delivered quickly from backcountry.com with no problems. Love these shoes!

These shoes have great arch support and are very comfortable. At first they were tight on the top of my feet. I kept wearing them and then actually soaked them in water, hoping they would stretch a little. They did and now are perfect. I have an average size 8 feet-not narrow or wide. They fit perfect now and I wear them all the time.
