Horrible horrible horrible trail running shoes. I gave them two or three chances. My feet have never hurt so much after a short hike run combo. I have bought nothing but ASICS for 12 years and these were the worst shoes I have ever gotten. If you actually use proper form and run on your toes and not heel (which is what you do when you hike uphill anyway), your feet will kill in about .5 miles and you will think about turning around. Also, there is basically NO tread for gripping rocks. The pictures are misleading. I slipped a few times on just sandy dirt....unreal!!!
