Lightweight, held up to water...however once soaked they got a little stinky...even after a wash and fan/air dry. I broke the loop on the back the 3rd time I wore them. They do fit tight and snug, so they are not slip on shoes by any means...made to be worn all day. Fit good to size (although I have 11.5, not sure why it wants me to review the 10's)
