I purchased the Drainmaker Water Shoe for a week long fishing trip out of Flamingo, Florida.  The fishing is usually a wet environment due to typical boat size and weather conditions and you are on your feet all day.  Day 1, I wore low cut socks but the socks did not drain as well as the shoes, so from then on, I went sockless.  The shoes worked great for wet conditions, but I discovered that daily shoe wash-outs would be helpful when wearing without socks.  They were comfortable the entire trip with no complaints even on my feet for a full day.  Great shoes and I would recommend them for wet environments.
