Shipping took about 3 days with Prime. I usually am a size 7.5 or 8 in shoes, and on account of my feet being a bit wide, I sized up and ordered a pair in a size 8. This size fits me a little big considering the shoe is a bit long and narrow in shape, but I figured the 7.5 would probably have been too snug and even narrower. These shoes are true to size, description, and true to the picture. Not only are these sandals comfortable, they are also very versatile, dress up or down. The sandals seem pretty resistant to water, but they do make this weird air suction sound when you walk if you do get them wet. I love them and am pleased with my purchase so far.
