These shoes are perfect for camp. They clean easily and dry quickly. My son has gotten them a bit muddy though, and you have to make an effort to get the muck out from inside the toe, or his toes are totally disgusting at the end of the day. He can abuse them as much as he likes though, and they still look good. He likes them a lot, very comfortable
