The Ugg Classic Ultra Mini boot, this Classic features everything you love about the original Classic Boot, like signature UGG sheepskin and a flexible, ultra-lightweight sole. The outsole of this product is a sugarcane EVA outsole, which is a responsible compound using sugarcane foam that allows us to reduce dependency on fossil fuels by replacing petroleum-based ethylene.
