If NASA knew that the type A was one of the few objects fast enough to break the sound barrier, it would be illegal to be this fast. The Type A is claimed to be Sauconys fastest road running shoe with the closest ground contact Everun-Blended mid-sole. This would be one of the other lightest options Saucony could offer for track sessions, not forgetting it’s ability to withstand mid to long distance running for those experienced with these lighter weight shoes.
SSL EVA is Saucony’s premium midsole material for lightweight comfort, rebound and durability.
XT-900 throughout the outsole is a carbon rubber material that offers durable traction.
IBR+ in the forefoot is a lightweight flexible material that offers enhanced cushioning and a responsive ride.
Engineered Mesh is updated on the upper to provide a sock-like fit that moves naturally with the foot.
Flex Film Overlays are made of a thin film that is welded to the upper for a snug, secure fit.
