PURPOSE: An auxiliary swimming equipment applying a buoyance to a shank portion is provided to have a safe swim by applying a buoyance to a shank portion which has the smallest buoyance in a human body. CONSTITUTION: To compensate for a buoyance reduction caused by men's erect walking, the body becomes equilibrium by making a foot portion not soaked for thereby maximizing the buoyancy. The equipment can be utilized as an auxiliary swimming equipment or life saving equipment by adding a degree of buoyancy and a portion to which the buoyance is to be adapted.
