1. Uggs were originally developed as a surfer shoe, and meant to be worn sans socks on the beach, so they aren't actually designed for colder climates. Because they are sheepskin they are actually warm, but there are so many other options out there.
2. Uggs are not waterproof and they leak. Imagine a big wet cold soggy sock on your foot. Now imagine them covered in salt stains.
3. Once an item has made it to everybody and their mother's mother, no matter how hip she is, it becomes ordinary.
4. People say that they are comfortable but you will be paying for it in the long term. Uggs are actually detrimental to foot health. The Society of Chiropodists and Podiatrists via NY Mag state "the flat soles leave the arches limp and can cause painful tendon conditions, such as a plantar fasciitis. The flimsy sheepskin casing makes a weak ankle cushion."
So as I was talking my friend out of Uggs, here are some options for truly cold weather I discovered:
Sorel was founded in 1908 in Canada and has been associated with cold weather footwear ever since. Sorel was first in the world to the first to combine leather uppers, rubber bottoms and removable felt liners back in the 60s for total warmth. Today they use Thinsulate to keep your toes toasty. I like the Sura but Style.com just featured Joan of Artic as their item of the week (these are rated for temperatures upt to -40!!!).La Canadienne, Montreal designed brand (Canadians know cold) has plenty of waterproof options that feature antibacterial microfibre linings to help your feet breathe easy and prevent funky odors. They also use environmentally-friendly dyes and protective agents as well as recycled materials for all packaging. I like the Chase, which is waterproof suede.

Last but not least, I think these Merrell Spirt Tibet High's are quite cute. They are waterproof and good for temperatures up to -20 Celsius (-4 Degrees Farenheit). Merrell is a performance oriented brand that's been creating gear for outdoors for over 20 years.
