Continuing to train. Exploring footwear. Merrills seem to hurtt my feet. Discovered their insoles have an arch that is too far back for my foot. My Adidas tennis shoes are better for walking but i doubt they would gold up on the trail. Might just buy a new pair of Army boots? Am going to try Soloman mid top hikers. Treadmill yraining while the temps are beliw freezing in TN. Just read an artcle about another old soldier who thru hiked last year and is a little older that I am. There is hope...
