The Drylock Split Toe 3mm Wetsuit Booties are best used in water temperatures of 49 - 58 degrees Fahrenheit, providing weightless and unrestricted stretch with the help of the Celliant Black. Quick-dry fibers keep the feet dry, and features such as the Drylock Ankle Seals, Ergo Strap Design, and Pull Up Ankle Loop ensure a water-free fit. Additionally, the Taitrex Outer Seam and taped seams provide added durability, and a 3D foot mold and single rubber bottom provide a contoured fit as well as board feel.
