29. adidas APS
This is one of adidas's finest running designs and it harbors a technology to rival the changeable inserts on the excellent adidas Fire. Between pads and pegs, adidas were killing them during the 1980s as they offered the consumer ways to personalize their sneakers way before the iD era. That unassuming but sleek upper betrays the application in the APS's midsole — the Antipronation and Shock Absorption System was a technology that allowed the wearer to alter the level of shock absorbing properties using a key — the hidden rods inside could be close to make the midsole more resilient, or farther apart to make it a slightly softer ride. Gimmickry done right.
