Customer Reviews

Comments: These shoes are awsome best running shoe ever
From: Anonymous

Comments: It takes a few runs to break in these shoes but once you do you won't want to take them off. The upper is form fitting and the zoom air sole is resilient. I have used these for runs up to 15 miles and they performed well.

Comments: I tried this shoe on with a quick jog over at a high school cross country camp sponsored by Nike this summer. While the upper is amazing like Nike claims, the sole of the shoe is what really matters for the quality ride a runner gets. It was super hard and firm. I am a forefoot striker and prefer to run in my Altra Instincts than the New Balance Minimus Trail 00 I trained in last spring. The Flyknit trainer simply needs to be flatter and softer for heel-strikers or forefoot runners. It is just too hard a shoe... no matter how great the upper design is.
