The Koolaburra by UGG® Lezly slip-on silhouette style slipper. Crafted from premium soft suede leather. Designed to be worn without socks. The interior is lined with plush, luxurious wool and faux fur for a cushioned, warm feel. A non-slip, flexible rubber outsole for indoor or outdoor wear. Finishing with stitch detail and instantly recognisable Koolaburra UGG branding to the heel. Tried on for a couple of hours on the carpeted floor. Sadly, they run small due to thick lining. In my opinion, they would fit comfortably UK 4-4.5 or a slim 5. **Outside sole is 24.5cm**
