These are great sandals. Not as much arch support as I had hoped for, but I have been spoiled by my leather Clarks flip-flops. The arch support is just fine, I just have ludicrously high arches, normal humans or even mildly high arched folks will be just fine with these. I also like the versatility of the velcro but I was worried of the aesthetics of it. Turns out from a foot and a half away you can't even see the velcro! (I have the black sandals, may not be the case with other colors.) So seeing as most folks are more than a foot and a half away from my feet I'm good!
