I bought the woody-max version this past year. They seem well made but are kind-of soft. I like a firmer sole I guess. Everyone tells me they'll last quite awhile. We'll see I quess.
Why don't you take a look at the irish setter boots. A guy I work with bought the rutmasters and they look well made.
