These men's adidas Springblade Running Shoes ensure an experience like no other. The Springblade Drive 2.0 propels the foot forwards for enhanced speed and a more energy efficient performance. 16 polymer blades line the outsole, individually tuned to maximise energy return. Larger blades in the heel enhance takeoff while smaller forefront blades aid cushioning. These blades are angled to push the foot forwards, as opposed to providing an upwards bounce like traditional running shoes.
