I've worn Asics for years now. I have their running cross training and now these. Unlike the others, these don't have the same amount of support so at first I didn't like them. When I took them on the trails I knew I made the right choice. You can feel more of the ground beneath you (rocks, roots etc) than what I was used to but they grip the ground so well. I feel stable running down hills and taking sharp turns in the dirt. I originally bought these to do a spartan race, but now they are my everyday trail shoes!
