Actually, last year they had a line of AWT shoes (
http://vanssnow.com/boots.php). But that page isn't current, they've ceased since then. Though, they do have these skate shoes in their "weather pack" (
http://skate.vans.com/product/weather-pack/) which apparently have weather resistant materials for those that skate in their garage all winter long.
I wonder if they're a good replacement for the Motleys, I feel like they might be less water-proof. Somewhat better for snowskating than normal skate shoes i suppose.
