Everything You've Always Wanted in a Boot...and Less.
It's simple. Our 2021 3mm Custom is the lightest, most high-performance piece of aquatic footwear in the world. Our most affordable Custom Series crushes competitor's top-of-the-line boots with instant response, barefoot feel, unmatched durability, and perfect custom fit that makes you forget you are wearing booties.
Our ongoing obsession with improving our products led to a completely redesigned neoprene upper on the Custom series, featuring our exclusive "EZ-O" cuff. The EZ-O cuff is a seamless O-ring against the leg, a design proven to greatly reduce water entry. Unlike other O-Ring designs, the EZ-O features a much larger neoprene panel, allowing more stretch in the opening and making the boots easier to put on and take off.
Sizing Tip: Order your regular shoe size or 1/2 size down. For example, if you are a size 10.5, order a 10. Women should order 1-1.5 sizes lower to convert from Men's sizing. So if you are a Women's 8, order a Men's 7. If you are a Women's 8.5, also order a Men's 7. NOTE: If your feet are exceptionally narrow or low volume, you may want to size down even more.
