Hands down the best set of fins in the world-Frankenfins! You are looking at the only pair in existance, about $35 plus the cost of two quick release straps. On or off in less than 5 seconds and no looseness or wiggle ever. Powerful yet with soft tips that are easy on the legs. The 10 year old boots (about 30% Aquaseal by now) will be upgraded next month. Ya just can't buy stuff this good over the counter.
