The Mellow Glow Sandal in brown is made of a padded sheep nappa leather in brown tan with a buckle ornament on the upper. The wide instep strap and toe ring insures your foot stays put.. The outsole is divided into two parts: a sturdier tan foam bottom, and a softer upper designed to absorb shock when walking. These are sculptural in design, like walking art; unique in form, and functional in design.
