The Nike Air Stab - Clerks Pack voltage yellow / white - black was apart of the Clerks Pack and is a bit different from the normal Air Stab, as it features a leather upper, as opposed to the usual mesh.�� The Air Stab logo is multi-colored to match the shoe’s brightness, and the red laces and toe are a nice touch.� This shoe is a great running shoe, but this particular model isn’t as great, as leather is not breathable, which may cause the foot to overheat. This is more of a fashion statement.
