Hi Redflare,
I have a pair of winter boots that are only a little taller than the ones you posted. They are Rocky, Mountain Stalkers and the best thing is that they are very non-slip. When I bought them the specs said they were "US Postal Service Approved Soles" for Non-slip and I find that they grip on ice much better than normal Vibram soles.
Of course I should have bought 2 pairs because now I see that this model is not listed on the Rocky website, although they do list models with "non-slip soles".
I wear mostly Danners now, they are great boots but the soles are more slippery on ice and hardpacked snow.
Good Luck,
Mike
