|3-finger polymer Meta-Shank™ aligns behind the metatarsals for greater forefoot flexibility and control when contouring, whilst retaining underfoot impact protection.||Multi finger polymer Meta-Shank™ aligns with each individual metatarsal for increased underfoot impact protection and flexibility.|
|Multi finger polymer Meta-Shank™ aligns with each individual metatarsal for increased benefit from the 'Windlass Effect', whilst retaining underfoot impact protection and flexibility.||4-finger polymer Protec-Shank™ provides the same great flexibility as the Meta-Shank™, but is specifically designed to protect the foot from the impact of the metal dobs in the OROC™ outsole.|
|The patented Dynamic Fascia Band™ (DFB) mimics the 'Windlass Effect' delivering a kick of energy with each step, helping the athlete to run faster and more efficiently.||The Meta-Flex™ is a groove in the forefoot of the outsole that provides a natural flex point in the shoe, allowing the forefoot to function naturally with each step.

inov-8's patented fascia band™ technology replicates the anatomical position of the plantar fascia ligament, and duplicates the function of the human foot's ability to utilize the "windlass effect". The inov-8 fascia band™ also replicates the benefits of the windlass effect of the human plantar fascia structure. Originating at the front of the heel's outsole the inov-8 fascia band™ extends forward along the outsole and divides, just as the human fascia divides, into five bands that terminate anterior to the metatarsal heads. As body weight moves forward onto the metatarsal heads and the toes begin to extend, tension on the inov-8 fascia band™ increases. When the heel leaves the ground, the inov-8 fascia band™ resists elongation of the medial arch and carries the entire body weight of the runner converting the shoe into a rigid propulsive lever.
