Just pulled the trigger on the mt extremes. how or what do most of you do to break them in. Am I correct in the fact that you just wear them for a short time each day as to not over do it on your feet? I think I have seen it takes upwards of 80 miles to break in. I'm working on that starting tomorrow, just looking for ideas. I also have the socks; a liner and an insulator sock also. Thank you for any ideas.
