Non-vented hydrodynamic design
for maximum propulsion. Balanced flexibility gives powerful
propusion without fatigue. Lightweight and comfortable.
Based on our knowledge of underwater motion dynamics our
SF-5000 and SF-5500 are designed to maximize energy
transfer to provide optimum underwater propulsion. The
side rails of these fins are made with a specially designed
compliant material that gives the entire blade a flexible
bending force. Dynamic stabilizers on the blade surface
and rails facilitate water flow which generates optimum
propulsion with minimal exertion. This racy design is made
from the most advanced and durable materials to pro-vide
ideal flexibility and stability.
SPECIALLY DESIGNED BLADE
TUSA fins feature a specially designed compliant material
built into each of the side rails giving the entire blade
a flexible bending force. Additionally, dynamic stabilizers
on the blade surface and rails smooth the flow of water so
the fin provides optimum propulsion with minimal exertion.
STRAP AND BUCKLE SYSTEM [PAT.]
Strap and buckle system feature easy to adjust straps with
quick disconnect or swivel release. You can slip easily in
and out of your fins without changing your strap adjustment.
FOOT POCKET
Super comfortable open heel foot pocket provides maximum stability and powerful propulsion. |
