I wanted a water shoe for walking in water at the beach or in a mountain stream so the bottom of my feet don't get messed up.  This basic shoe fits the bill and has a nice solid sole.  I typically wear size 12 and, on a rare occasion, an 11.5 and I ordered a size 11.  They are a nice snug fit with my toes right up at the front, which is how I think they should fit.  I don't want room for my foot to move once I get in the water.  They seem to be of the same quality as my wifes speedo water shoes and I think I'll get some good use out of them. Would recommend!
