People On Horses® presents sheepskin-lined bell boots. Choose from a variety of color combinations. Sheepskin is an ideal material for shock absorption, temperature balance and relief from friction and pressure. By allowing air to circulate between the hair and the leather of the sheepskin, the sheepskin forms a protective air cushion that also prevents moisture seeking mold from propagating. We use actual sheepskin in natural, black and golden colors. We insert a 3 millimeter layer of SBR (a synthetic rubber) for additional protection. The natural sheepskin can vary in color and may occasionally have natural spots.
