My Canadian Tire snow boots are still holding up. Think I paid around $75 for them. It's fairly easy to bickle my snowsahoes on over them. Of course I don't need snow boots too often, living here in the banana belt.
As for socks I swear by Smartwool socks and wear them year round. Good cushioning, very durable - I've had a couple pairs for three or four years. They're very comfortable, even in warm weather. When I wear cotton socks now I'm displeased by their clamminess when they get damp from perspiration.
