TECHNOLOGY

The forefoot gridwork pattern provides movement on impact enhancing shock absorption and rebound.

The inside of shoe next to your heel bone is a softer density foam that forms under pressure to cradle and stabilize your rearfoot. As you wear the shoes, the overall drop will settle from 6mm to 3mm. This allows the foot to land more parallel to the ground for a more efficient natural running gait.

Stack height: 20mm – 14 mm
Drop: 6mm *** Adjustable internal heel cradle conforms and settles to a 3mm drop with use.
