With its soft sheepskin and barefoot feel, the Classic II features an ultra-lightweight cushioned outsole. Each boot is built to move the way kids do – running, jumping, and whatever else they get into – with a flexible rocker-bottom shape that's perfect for all-day play. Pair with our adult sizes to extend the style to the whole family. 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.
