In Australia, the Ugg-style sheepskin slipper is a very popular shoe worn by women of all ages and sizes (and even by men). The Ugg sheepskin slippers are suitable for indoor or outdoor use mainly because of its natural insulating properties. It’s also quite fashionable, though the only ‘fashion statement’ it’s really making is that you love comfort and warmth!
The only time you might want to think about wearing another type of footwear outdoors is if it’s been raining heavily or if there’s a lot of snow on the ground. If you’re wearing Uggs that are made for an outdoor environment, they’ll be suited for a more active lifestyle and more rugged conditions.
