I have two pair of birksdals I’m probably about to put up for sale. Both are 9.5 4 flex.
The first pair is leather and have about 125-150 miles on them they have a new pair of super feet in them never used.
The other pair is brand new with 50 miles on them from a recent backpacking trip. These are non insulated leather/canvas with a new set of super feet with the same miles. I probably still have the original inserts for the new ones some where.
I have a pair of 10’s coming to try on for comparison. I don’t know if my feet have grown or what but both boots are fitting snug and I’ve worn these same style and size crispis for the last 5 years. I have absolutely loved these boots and have used this style whether it’s hiking, hunting low country elk, high country elk, or chasing caribou in the brooks range.
