Webfoot Attachments for Swimmers
In order to make the feet more effective in swimming, webfoot devices are frequently used. A simple arrangement for this purpose is shown in the illustration. It consists of three thin sections of metal, or wood, fastened together on the back side with spring hinges, which tend to remain open, thereby keeping all the sections spread out in one straight surface. The center section should be cut to conform closely to the shape of the foot, or it will produce considerable resistance during the onward stroke of the foot, and tend to stop the forward movement of the swimmer. Straps should be provided for attaching the device to the foot; one to fit across the toes, and the other adjusted around the ankle by a buckle.
Device for Attaching to the Feet to Work Like Webfeet
When using the device, the upward or forward stroke of the legs will cause the wings to brush against the water, creating sufficient resistance to overcome the slight force of the springs, thereby pushing the wings parallel with the direction of the stroke. During the opposite, or pushing, stroke, the resistance of the water combined with the opening tendency of the hinges will quickly spread the wings out flat, greatly increasing the effectiveness of the feet.—Contributed by J.
