These boots are crafted with UGG’s famously soft sheepskin, which naturally wicks away moisture so you can wear it anywhere – both indoors and out. The outsole of this product is either a sugarcane EVA outsole, which is a responsible compound using sugarcane foam that allows the company to reduce dependency on fossil fuels by replacing petroleum-based ethylene, or a Treadlite by UGG outsole. Only used several times and are like new.
