Comfortable fit but soles crack
I work for a Federal Land Management agency and spend a considerable amount of time out doors. I have had many different brands of bots over my 30 year career including custom boots. The GTX is very comfortable right out of the box but within a couple of months the soles begin to crack on the ball of the foot. I have had 4 pairs now and every pair had cracked one pair within 3 months. I work with 3 other biologist and all of their boots have cracked as well.
