This kit brings together the four pieces you need to build or refresh a TUSA HyFlex Switch Pro fin: the Switch Pro blade set, a spare foot pocket set (two pockets), a bungee strap, and the hardware kit that holds it all together. Whether you’re assembling a full fin from parts or replacing a worn piece, everything here is designed to work as one system.
The bungee strap adjusts to five positions so it fits a range of foot sizes, has a comfort-flex hinge, and includes a rubber heel grip with a finger loop for a quick, secure fit. It’s built to work on most open heel fins on the market, not just TUSA’s. The hardware kit rounds things out with a 3mm Allen wrench, four O-rings, and four stainless steel screws, so you have what you need for routine maintenance or a fuller rebuild, and it’s compatible with all TUSA HyFlex modular fin models.
Pick your size — XS, S, M, or L/XL — and your color — Black or Energy Orange — when you order. Combining the blade set, foot pockets, strap, and hardware in one purchase means you’re not hunting down separate parts to get a complete, properly fitted fin.
