Abstract
Abstract A slipper designed to leave the wearer's toes exposed for enjoyment or for treatment such as a pedicure is provided. The slipper has a sole which may be of flexible and pliable material or may be relatively rigid. A cushioned insole may also be used and connected to the sole. At the margin of the rear portion of the sole, a heel containing means is connected. The heel containing means is formed of a fold of material with the fold being joined to the sole. The free edges of the heel containing means are seamed together while also forming a passage for a tying cord or ribbon. The tying cord or ribbon is made captive in the passage by stitching it to the heel containing means at one point to prevent inadvertant removal of the cord or ribbon therefrom. An adjustable strap is connected to the margins of the sole so as to extend across the instep of the wearer.
