These water shoes are the best! If you read reviews and understand that at 1/2 size you need to go down rather than up, you'll be happy with that. However, I still have some leeway. If I went down a little less they would be too tight. They have withstood white water abuse for 2 weeks! They look really cool and people have been asking me where I got them because they're tritoes and they look unique! It's like walking barefoot without an arch, but that's to be expected. I walked in it for hours without rubbing or blistering. Sand will come in from the top and you'll have to flush them out, but they let water through the bottom through little mesh holes to keep sand from getting in. These shoes are awesome and if you are thinking of buying them you have won. Have no pity on these babies!
