Has anyone on here run in K-Swiss shoes? I know they're making a push into the running and multi-sport markets, sponsoring the LA Marathon and partnering with Trek to form an elite triathlon team, so I'm wondering if their product is actually any good? One of their shoes is customizable, with different inserts for different amounts of support and weight for different types of workouts; it sounds like it might be a little gimmicky, but could also be a good idea. Thoughts, letsrun?
