I think I got a good value for $70 delivered from OnLineShoes.  The shoes are wide, tall and very warm. Since the lower section has rubber coating and the top can be tightened, they should keep my feet dry.  My size is 6.5, so I had to order size 7, which will work.  I can tighten the middle section and wear heavier socks, to keep the foot movement at the minimal.  Going .5 size smaller was not an option for me.  I tried it and I felt the tip of my toes hitting the front end.  Also, they are a bit heavier than I would like them to be, so long walks/hikes in the woods might not be overly comfortable.  In summary, given the price, its warmth and durability, its use for snow shoveling and taking my kids to a snow hill for sliding, they should work.
