adidas Springblade Drive 2 Running Shoes - 8.5 - Black

UPPER The Adidas Springblade Running Shoe's 360-degree air mesh upper accommodates miniature perforations coupled with a sturdy lacing system, to deliver a shoe that is simultaneously breathable, flexible and robust. Air is allowed to permeate the interior, whilst a comfortable inner lining sits agreeably against the skin to minimise the risk of chafing and consequent blistering. An external heel counter holds the foot in place for a secure, reliable lockdown throughout. MIDSOLE The Springblade Drives principle performance element and party piece is its midsole. 16 polymer blades replace traditional foam cushioning compounds to deliver a unique, revolutionary approach to cushioning and propulsion, with a striking aesthetic to match. Each blade is aggressively appointed in such a way that energy obtained during the heelstrike phase is returned during subsequent phases of the gait, culminating in an explosive toe off that propels the wearer forward. Energy is recycled, compression set is eradicated and smoother, more efficient runs abound; each blade instantaneously reacts to any environment, compressing and releasing energy. OUTSOLE The outsole of the Springblade is engineered with adiWEAR technology for durability in high wear areas. An external heel counter stabilises the initial heel contact for a smooth ride.
