## Abstract

A shoe cover with a replaceable skidproof component comprises a shoe cover, a plurality of skidproof bases, and a plurality of replaceable skidproof components. The shoe cover is integrally formed of elastic and ductile material and extends upwardly from a front edge and a rear edge to form a front cover-stopping portion and a rear cover-stopping portion. The front and the rear cover-stopping portions have a plurality of openings that form at least two stopping pieces. A containing space is formed between the shoe cover and the two cover-stopping portions. The skidproof bases are buried in a bottom of the shoe cover. The replaceable skidproof components are mutually locked to the skidproof bases. The shoe cover with replaceable skidproof components provides a simple structure, easy usage, and is inexpensive to produce.
