Adidas Springblade

Adidas will be releasing their $180 Springblade sneakers, which feature “individually tuned blades engineered to help propel runners forward with one of the most effective energy returns in the industry.” These have to be the wildest-looking footwear design since Reebok’s knobby ATV 19+. The Springblade’s sixteen polymer fins, blades, flaps, whatever you want to call them, are meant to help turn downward force into forward motion, and Adidas’ Innovation Team reportedly tested “hundreds of materials” to get the desired bounce.
