"No Ph.D. Required." The Nike V-series was a lineup of shoes for women including the Venue, Vengeance, and the Vortex. The Venue was the most stable of the three, followed by the Vortex. The Vengeance was a lightweight cushioned shoe.
The Vortex was apparently the best of both worlds according to the ad print, and usually stability shoes work for a majority of runners so that makes sense. Thanks for looking, and leave a comment!
