A modern interpretation of our icon, the Ultra Mini reaches new heights with a leg-lengthening 2"" platform. Offering a bolder look than ever, it's made with the same rich suede as the original, plus our UGGplush wool blend for signature softness. The outsole of this product is either a SugarSole outsole, which is a responsible compound using sugarcane foam that allows us to reduce dependency on fossil fuels by replacing petroleum-based ethylene, or a Treadlite by UGG outsole. Treadlite by UGG Proprietary compound which increases cushioning and traction for a supremely lightweight, ultra-durable sole.
