It is is worth it to figure out your sizing and then just buy online as they only sell through small retailers. You can find these for really good price on clearance. For example I got these for $140 CAD at the end of last year from here.

They only have one size left and reduced it to $100 now. Considering an iron ranger costs $450 CAD that is a steal for a made in North America boot.
