Our Classic Ultra Mini is one of the most coveted of our Classics. Built-in flair with a lower shaft which makes for easy on-off wear. Pre-treated to keep it looking better for longer, this Classic features everything you love about our original Classic Boot, like signature UGG® sheepskin and a flexible, ultra-lightweight sole.
The outsole of this product is either 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, or a Treadlite by UGG™ outsole.
This product was made in a factory that supports women in our supply chain with the help of HERproject. This collaborative initiative creates partnerships with brands like ours to empower and educate women in the workplace.
