Swimming aid

A swimming aid comprising a flexible fin member having a first end and a second end joined by two opposing side edges, said side edges extending from said first end to said second end;

• and an underlying attachment means connected adjacent said first end of said fin member and adapted for attachment to a portion of the anatomy of a user, whereby in use said fin member overlays the portion of the anatomy of the user and extends from said first end free of said attachment means, longitudinally of said portion which it overlays, to said second end, and with said opposed side edges, at least at said second end, extending outwardly on both sides of said fin member, away from the center line of said portion which it overlays, such that during a power stroke of the user, said fin member adopts an extended position, but during a return stroke the fin member flexes into a substantially collapsed position away from the said portion of the anatomy of the user to reduce drag by the flexible fin member.

A swimming aid comprising a flexible fin member;

• and an underlying attachment means connected adjacent one end of said fin member and adapted for attachment to the shin of a user, with the attachment means located adjacent the knee such that the fin member extends free from said attachment means in the direction of the foot, whereby, in use said fin member extends along substantially one face of the said shin and has edges which extend outwardly beyond both sides of said face, at, at least, its free end, such that during a power stroke of the user, the relevant water flow is over the surface of said fin member which extends outwardly beyond both sides of said face to an extended position, but during a return stroke said fin member flexes into a substantially collapsed position away from said shin to reduce drag by said fin member.
