First off, I'm not a neoprene kind of gal. But a friend asked me to escort him on a paddle board as he was doing an English channel qualifier (that is a 6 hour swim in <60F water) carrying nutrition and what not. These were the absolute best. My toes never went numb and when I got thrashed coming into shore they were high enough that I didn't limp out with a load of sand between my toes. Love these!
