I know they are not directed towards just running, but from what I have been told by Ches (cousin of mine), he says that the spikes are amazing and better than the victory's. They have not released the spikes are far as im knowledgeable but i'm sure when they do they will change the game.
Also, the Razor 3s, I have them; AND THEY ARE BY FAR 100% BETTER THAN THE VAPORFLY.
And the ride 7s, BEST TRAINER OF ALL!
