Mares' Razor Foot Pockets are designed to be worn with a 3mm neoprene sock. If you are wearing these fins barefoot, use the next size smaller fins.

The set has everything you need for fixing your Razor and Razor Pro fins.

This preformed insole can make a Razor Foot Pocket one size smaller. Cut along the lines on the rear side of the insole to adjust length. Ideal for those who have trouble finding smaller fins, or people who want to use the foot pocket with boots of different thicknesses.

A replacement blade for the high-performance Razor Apnea - choose between medium and soft strengths.

A replacement carbon and fiberglass blade for the highly responsive Razor Matrix fin. Choose a soft or medium strength fin depending on your preference.

The tapered Razor Pro blade is made from the best technopolymers, meaning excellent agility and elastic performance. These blades channel the flow of water thanks to their 'V' shaped tip, preventing slipping.
