I have a pair of used Kenetrek's as the title describes. I wore them last season thinking I just needed to break them in. Took them on one scouting trip this year with about a mile hike in and out, and blisters on the heels again.....I need to get a 10.5 medium or narrow. They only have about 20 miles on them. I just finished up washing them in the photo before I grease them with Kenetrek brand grease as I did when they were new and once after last season, that is once I can find where my wife hid the boot grease from me......also my wife HATES clutter, so the original box is no more....... $275 OBO TYD. Thanks for any interest.
