I have a pair of Kennetrek Mountain Guide size 12 boots for sale. Have less than 30 miles (mostly mowing the lawn and walking around town) - they don't fit my feet well so am going to go with Lowa's instead of Kennetrek. 400 grams of Thinsulate - you can see full description on Kennetrek's web site. $250 tyd. Money order only no paypal. Text 307-262-5734 for more pics/questions or e-mail [email protected]. I read rokslide a lot but haven't posted much.
