FWIW, we just got hit with some snow in NC (about an inch) and I made it safely to work on my RE050s with 15k miles on them. They're just fine in cold weather (it's been 20F-30F here recently) - but if you live in an area with regular snowfall, I probably wouldn't recommend them.
Or, buy them now and use them when warmer weather comes around :thumbsup:
