The HyperFlex 3 mm VYRL is a soft-sole surf boot with a square split-toe design. Fusion-welded seams and a quick-drying interior are intended to keep the boot comfortable through colder sessions, while the layered outsole, heel, and toe construction balances flexibility with support.
A heel pull loop helps with entry. Choose the size for secure foot hold without cramping the split toe, and verify any intended fin compatibility before diving; this model is marketed primarily as surf footwear.
