Our ZhikGrip II straps are designed to connect and lock with our boot range. Together they provide the best connection to your boats dynamics, allowing you to hike hard for longer, while keeping your foot relaxed. Using highly durable Nylon and Rubber construction the interlocking stud pattern allows for extreme grip at any angle or position. *Straps sold separately, not in pairs. Before buying please note that: This "Classic" size strap fits pre-2013 Sunfish designs. If you have a 2013 Sunfish or newer please purchase our Laser Strap.
