The Alaska boots look lively and they look like they should last pretty well, as they have a water resistant finish, but I would be cautious with other Reiker boots because most are not leather. That might be an advantage to some (for ethical reasons) but I've wasted too much money on boots with synthetic uppers which look awful after a month or two. Personally I would choose something with a leather upper, you might pay a bit more but the difference might be a couple more winters wear. Is there anything by Merrell, Josef Siebel or Ecco etc?
One of my pairs are 4 years old (not leather) and has been worn to death, the uppers have no sign of wear at all, they really are beautifully made, check out the reviews on Amazon etc, once converted you won't go back.
Merrell boots otoh are some of the shitest wearing boots I have ever come across, and are not possible to re-sole.
