Nike Sportswear has recently used "Vac Tech" leather on several Nike Air Force 1 models this summer. Having an unusual wax, clay like appearance and texture that is approved by sneakerheads, "Vac Tech" might become a staple for Nike in the long run. Coming soon in the fall but available now for pre-order at KicksCrew is the Nike "Vac Tech" Premium Pack in Haysack/Birch. The pack will include three popular Nike models, the Nike Air Max 90, the Nike Dunk High, and the Nike Air Force 1 High. Will you wait for these to drop in the states?
