Howdy, I got new pairs of each so the old Xcel ones are up for grabs. The 7 mm have a spot on the upper near the ball of the foot where the neoprene is starting to delam The 5mm are totally solid. Both pair are size 12 men's, do not leak nor do they smell. They are a few years old. Free. DM me your address and I'll send them along. Thanks!
