Nephew got them; I borrowed & wore in head high surf for body surfing & rip avoidance... I promptly snapped inside left buckle off. NOT broken, just the plastic pins came out of the holes. We returned to store ((1) day old) and he got fins replaced for free & I bought a pair b/c I liked the power in heavier surf.Next day same thing happened to me. I returned & got Makapu's...I liked the leash & they were comfortable & fast. Weak spot however in construction; they will NEVER last b/c of weak link in clip. If you have them in your hand in store, you can pull off that clip w/o too much effort, so imagine in a crucial situation...
