Under Armour releases Spieth 3 golf shoe with improved stability and biomechanics consideration

Under Armour, working with input from Jordan Spieth, has released its Spieth 3 golf shoe, out today. This is the third generation of Spieth's namesake shoe, and it was created with a focus on the biomechanics of the swing with the help of J.J. Rivet of the European Tour Performance Institute. Under Armour focused on Rivet's findings on torque and rotation during the golf swing, and what that means for stabilizing the foot.
