I'm a Smart Wool guy, but will have to try the Drymax stuff. I need to try out some new trail shoes. I'm 6'4" and around 215 and for the road usually use motion control or stability models. Right now for the trail I have a pair of Saucony Pro Grid Trail TR. They're stability shoes so they have a higher heel, meaning more risk of ankle turns in the terrain. I'm going to research some neutral (lower) shoes that may be able to hold up to my big ass pounding them all day. If any of the peeps you do your trail runs with are big, I'd love to hear any suggestions they may have.
