TUSA HyFlex Zoom SF0111 split fins
The HyFlex Zoom uses split blades with six vents and an angled blade design. The modular HyFlex interface allows compatible components to be exchanged.
- Split-blade design with six vents.
- TUSA flex blade material.
- Angled Blade Design.
- HyFlex modular system.
- Bungee heel straps with five adjustment positions.
- Shaped heel cups.
Choose the fin-pocket size with your intended boots. The five strap positions adjust heel retention; they do not change the moulded foot-pocket size. Fit, technique and conditions affect finning effort.
