Originally released in 1986, the Adidas APS was one of the first running shoes that came equipped with an adjustable cushioning technology. Accompanying the APS is a special key that you would place into the heel to adjust the various cushioning options in the midsole. True to the exact specs of the original, the Adidas Originals APS in Running White / Collegiate Red / Lone Blue is now available for £90 at Oi Polloi.
