What pair of Vibram Five Finger shoes should I get?

Alright so I'm getting a pair of SPEED Vibram Five Finger shoes. If you don't know what Vibrams are you should seriously consider in getting a pair. ANYWAY, I will be in high school next month and will be doing track, so what I ask of you is should I get this pair of is there a better pair fitting my needs. TAKE NOTE that I will need school appropriate pair and SPEED shoes look the best for that. Opinions?
