I have a few different pair of teva sandals, these by far fit the best. I wear a 6-6.5 and ordered these in a 6 based on the others I ordered and let me tell you, these are crazy comfortable!  I managed to snag a pair in black and grey for around 25 bucks ( love teva, but love a deal on them more ) even if you pay full price for these , they are absolutely worth it! They are the only shoes I take hiking, floating, and just wearing around. Love the arch support!
