Carbon shoe inserts by Molchanovs are available to harden the soles which improves the fins’ response. Although the carbon inserts are just 1 mm thick, they add to your size: so if you are comfortable with size 41, you should order 42-44 foot pocket with inserts for your comfort.

The blades are made to withstand strong underwater moves in any direction and consequently provide powerful thrust. However, don’t walk with the fins on rough rocks and don’t drop heavy solid objects, such as cameras with underwater gear, weights, etc. – the blade could crack or break. We suggest washing off salt and keeping the fins away from the strong sun and heat.
