JBL Dive Socks designed these asymmetrical socks to perfectly contour the foot. These dive socks provide a soft, cushioned buffer between the foot and dive fin for all day use. The soles feature a rubberized traction pattern for increased durability and grip. This means maximum transfer of energy from each fin kick. They feature 3mm neoprene construction with Super Stretch nylon panels for enhanced flexibility in areas you need it most. It is due to this blend of materials that make these socks the perfect combination of warmth, fit, and flexibility.
