Abstract

A flexible protective cover for boots, shoes and the like to protect the wearer from injury from a chainsaw. The cover has a lining of layers of high modulus fiber fabric between an inner layer and a outer layer of durable fabric. The lining is secured between the inner layer and the outer layer by a quilt-like stitching. The protective cover is folded to conform to the instep of the shoe and extend to the ankle. A strap and fasteners are attached to the cover to permit the cover to be secured over the shoe in a rapid and easy manner. In a preferred embodiment, a tab is formed on one side of the cover and a bail is attached to the other side of the cover. The tab is pulled through the bail and returned approximately 180° to the one side of the cover. The tab is held by quick-release fasteners to the one side of the cover thereby firmly securing the cover longitudinally to the boot or shoe. Transverse fastening means are provided between the lower edge of the side portions of the cover and the sole plane of the shoe. A cord formed of lining fibers is attached to the lower edge of the side portions of the cover to provide additional protection to the edge of the cover.
