Abstract
A monofin comprising a swim blade having two adjustable foot pockets for attachment to the feet of a swimmer. The foot pockets can be positioned on the blade to conform with the optimal foot positions for a particular user. The blade itself has a central v-shape, so that when the foot pockets are attached to the blade each pocket leans inwardly towards the other. The blade has upturned outer wing sections to reduce the resistance during the retracting kicking motion. The blade is pitched to channel the flow of water rearwardly and centrally, focussing the water to a point behind the swimmer.
