Uggs will get ruined in the rain, or snow. The material isn't waterproof, so it will stain, soften, and gradually rip. They were never designed to get wet, as said below. They're called ''Uggs'' because they were the non-fashionable, kinda ugly looking boots that surfers wore to keep warm when they got out the sea.You can buy it from http://www.cheapugboots.co.uk.
I don't think you should use your Ugg Boots for snow, because it can get stained ^.^ , but when my Mom bought me some the Cashier offered us some spray. It's like a Conditioner and Spray thingy (: . Maybe you should look on the Internet for it, or just go to the store, and ask for it.
