Palau SAF has a very soft, short blade and a foot pocket that allows it to be put on in seconds, even when in the water. * What is more, the foot pocket has been designed to accommodate at least 3-4 consecutive sizes and allow the fin to be worn over thin footwear. * The strap has a strong ring on the upper part to allow reversal of the strap itself or to fix the fins to the body or the equipment.
