CUSHIONING

  • 2nd Generation Action/Reaction Technology is utilized in the heel and forefoot. The external actuator lugs are wider in the forefoot for increased stability and are designed to press into recessed chambers with an elastic membrane to absorb shock energy. During toe-off, the lugs are engineered to release the stored energy for increased forward propulsion.

MIDSOLE

  • 2nd Generation Action/Reaction Technology is utilized in the heel and forefoot. The external actuator lugs are wider in the forefoot for increased stability and are designed to press into recessed chambers with an elastic membrane to absorb shock energy. During toe-off, the lugs are engineered to release the stored energy for increased forward propulsion.
  • EVA is an industry standard midsole material designed to offer durable cushioning.
  • Support Chassis is located at the midfoot and is a thermoplastic device meant to increase stability.
  • Met-flex is located at the forefoot and is a flex groove intended to allow the foot to flex naturally.

UPPER

  • Closed Mesh covers most of the upper and is a breathable material engineered to keep small debris out.
  • Overlays are anatomically located to provide a secure fit.
  • Metatarsal Stretch Panels are positioned at the medial and lateral forefoot and are designed to reduce irritation.
  • Slip-Proof Laces
  • Sockliner is designed to increase energy return and protection.

OUTSOLE

  • Carbon Rubber Heel is engineered for high mileage durability.
  • High Density Rubber is utilized in the forefoot and is intended to provide a long lasting outsole.
