I originally purchased this shoe to use as my distance shoe as I began to feel more impact with my Altra One 2 when going distances greater than 16 miles.  While the shoe is extremely comfortable, I found a serious problem with it when trying to run longer distances.  I experienced bruising on the fifth metatarsal right near the point of the proximal phalange.  I found this surprising given the fact that I never experienced this issue with my One 2, One 2.5 or my Torin 1.5.  This shoe has been relegated to my non-workout shoe (walking around) and strength training.  I was expecting the same type of shoe as my One 2.5, but with more cushion for longer distance.  That is not what I got.
