I wanted to buy these for a trip to the beach because I wanted something I could wear with a dress and also wear casual - I wasn't sure if I should after reading reviews that said the straps were tight. I have fairly wide feet and also have to size down for sandals - I wear a 7 in athletic shoes, need a 6 1/2 in flip flops(hard to find) so I buy a 6. I went with the 6 and they are perfect!!! I put them on right away to break them in like other reviews said. A little tight at first, but after about an hour wearing them in house - they felt fine. I walked the boardwalk in them and many beach blocks all week and they were very comfy - straps did not hurt my feet at all. Very pleased!!!!
