Koolaburra by UGG Women's Koola Tall Boots - Waterproof Winter Snow Boots for Women, Comfortable & Warm Suede Booties with Faux Fur Lining - Perfect for Cold Weather, Snow Days & Outdoor Activities

I wear US size 9 (40 cm) so I ordered this size and it fits perfectly. The only thing I’d change- I’d order wide version because it wouldn’t be felt on my foot at all. Nevertheless, the ordinary width is good too, I wear thick socks in winter and the boots are comfortable with them. Not too mention that they’re very warm and I like that they’re made of more rough suede than usual UGGs which makes these particular boots to last longer. Highly recommended.
