Although there are many great features to this fin, look at the armadillo hinge of grooved material on the top of the foot. This specialized feature absorbs energy from your kick and releases it again at the end of the kick cycle for a more efficient kick and reduced strain. Includes Spring Straps for easy on/off.

Features: 

• Armadillo Power. Armadillo Hinge at the blade base absorbs energy on the downstroke and releases it on the upstroke, giving you a power boost on every kick.
• Secure Spring Strap. The sturdy, padded spring strap keeps the fin snug on your foot, your fit great, and your heel protected from abrasion. Features finger loops for easy on/off, even while wearing thick gloves.
• Full-Pocket Design. High comfort, no booties required. Full-pocket fins give you increased perception of your kicks’ effect on the water. Foot pocket is made of soft material of varying elasticity for comfort and efficiency.
• Hydrodynamic. The rubber side ribs channel water down the length of the fin to reduce drag and maximize the efficiency of your kick.
• Reduced Strain. Why strain your foot with unnecessary bending when the fin can do the dirty work? This fin’s mid-foot flex joint attaches the blade to the side of the foot pocket to aid in energy transfer and reduce strain on your ankles and toes.
• No-Slip Sole. Underside has excellent grip to reduce the risk of slipping on deck.
