摘要

PROBLEM TO BE SOLVED: To facilitate the replacement of the sole of conventional footwear, the replacement of a tread portion due to wear or the removal of water or stains.;SOLUTION: The footwear is separated into an independent footwear-sole and a piece of independent instep-footwear. The instep-footwear is designed to be used indoors and outdoors and in winter and summer. For the footwear-sole, the forward trodden portion and the trodden heel portion are made separable by using a Velcro fastener. The trodden heel portion is oval and the wear thereof is uniformed by replacing the front with the rear and the right with the left four times. The instep-footwear and the footwear-sole are connected with a Velcro fastener for walking. The right and left of the footwear-sole are equal in size and flat. By replacing the front with the rear and the right with the left, the wear is countered and the sole can be used indoors and outdoors. Water or stain can be removed by opening and closing the fastener of the instep-footwear.;COPYRIGHT: (C)2005,JPO&NCIPI
