Hopefully you'll be a little more explosive than Rich "Mr. 6.25" Eisen in these things. The official shoe worn by the players at this year's NFL scouting combine, the Under Armour Combine II Trainer ($80) sports a TPU Propulsion Plate that keeps you on your toes (literally), an engineered hi-shine synthetic and mesh upper for lightweight breathability, a comfy ArmourForm insole, full-length ArmourBound cushioning, and a propulsion-y outsole to better your chances of going in the first round.
