Query: Last a month, DO NOT BUY!!!

These do not stand for working in the sand, they are not waterproof either. If the powder like sand can get inside and dry out your feet, then water would have not stood a chance. These are "you get what you pay for" boots. The back ripped off in less than a month, the construction is very poor. DO NTO WASTE YOUR MONEY!!! Buy Converse.
