Just a suggestion re: the AM41’s (this is from someone who has previously owned/owns Vans/5.10s/AM40’s etc). Personally, I like ’em, and they’re reasonably water resistant. However, I don’t find ’em as warm as 5.10s, or even my old AM41’s. I think the problem is that the midsole is a bit thinner than the other shoes.
Couple of top tips if you want to improve their cold weather performance on the cheap – pop some insulated insoles in, and if you want to stop water getting in thru the perforated areas, rub a bit of clear boot wax/dubbin in to fill the perforations in. If you try the latter, it needs to occasionally be reapplied, but it works a treat.
