The Women UGG Classic Ultra Mini Fur Lined Boots are the low version of the Classic. These fur lined boots in 17 mm double-faced sheepskin have a 9 cm shaft that stops just above the ankle: you keep the warmth, without the bulk around the calf.

It's the sheepskin that makes the difference. It stays soft against the foot and holds the warmth when it's cold outside. The insole, in wool and lyocell, works with socks or barefoot.

Underneath, the Treadlite sole stays light and flexible, with lugs that grip on winter pavements. A water-repellent treatment protects the sheepskin from light showers. They are not rain boots, but a drizzle won't force you to change shoes.

On weekdays they go with straight jeans or leggings. At the weekend, at the market or travelling, with joggers and a chunky jumper. The heel tab at the back lets you pull them on in one go.

Sizing: the Classic Ultra Mini fits true to size. The sheepskin packs down a little with wear, so if you're between two sizes, take the smaller one.
