Mike Stewart Viper Swimfins NOTE: FINS WITH YELLOW DOT COLOR HAVE A STIFFER BLADE. OTHER DOT COLORS HAVE A MORE FLEXIBLE BLADE! Wider, shorter blade design for quick acceleration. Beveled sidewalls improve control. Delta tail design; which I have found to enhance control and minimize drag. Maximum foot pocket drainage eliminates any sand or pebbles in your kick. Rivet grip tread enhances footing on slippery rocks yet won’t snag on coral or sharp objects. All VIPER surfing fins float high and are visible in the roughest surf conditions. All VIPER surfing fins are made of superior 100% natural rubber compounds. Boxed in a sturdy recycled cardboard and printed with soy base ink.
NOTE:  Black with Yellow Dot and Royal Blue with Yellow Dot MS Vipers are made with a stiff rubber compound
