The shoes are VERY loose fitting with no support, in both the front strap, as well as the back. I even ordered a 1/2 size small, and followed specific measuring instructions sent directly from the seller. I do not have thin feet by any means, simply average. ***Be aware*** I tried the shoe on once, on a carpet, on the same day they were delivered to me, and the seller is VERY strict and in personal about refunds, will only do exchanges (even though their shoes simply do not fit my feet) and even said customers are responsible for paying return shipping. \n\nThere is literally nothing wrong with the sandal, and no reason to not honor a same day shipped return for a very expensive sandal. So, the seller will take back the shoe to resell, but will only send a different one, no refund. \n\nHopefully they have a better recommendation!
