There's some closeout Lake LX140 boots on Ebay right now, I got a set for $50 shipped:

If conditions are wet or exceptionally, I'll probably still put waterproof booties on over the Lakes to keep them dry and in still air.
Oh, and like
Leebo says, thrift stores are great. Wool sweaters galore, athletic pants, wind pants, and sometimes nice jackets show up there too.
