Abstract
Abstract A swimming shoe composed of a shoe body, several water-resisting flanges and an attached swimming-assistance device. The shoe body has the shape of a sandal which has a shoe bottom, a shoe surface, two fixing plates and a fastener. In the vamp of the shoe there are two fixing sets which both have a fixing set and a button to attach the water-resistant flange. In the shoe body, the fixing plate can hold the swimming-resisting device. This new device will not interfere with walking on land and also can be used as an aid to help the swimmer to swim faster.

Claim 1
Independent Claim
218 words
A swimming shoe comprising: a sole; a sandal strap extending across the front portion of said sole; a strap-like fastener extending around a rear portion of said sole from said sandal strap; a fixing plate extending upwardly from the edge of the rear portion of said sole on each side of said sole and having a hinge mount on the upper end thereof and a fastener member on the upper end thereof; a water resisting flange pivotally mounted on each hinge mount for free swinging movement from a position against the fixing plate to a position laterally outwardly of said shoe; and said sandal strap having a pair of hinge mounts on the upper portion thereof and a further water resisting flange pivotally mounted on each hinge mount for free swinging movement from a position against the sandal strap to a position laterally outwardly of said shoe; all of said water resisting flanges having a free end which, when the flanges are against said fixing plates and said sandal strap, terminate short of the bottom of said sole, whereby when the sole of the shoe is on the ground, the free ends of the flanges do not touch the ground and the wearer can walk in the swimming shoe in the same manner as in an ordinary sandal.
