CUSHIONING

  • A-Bound is a recycled, environmentally friendly midsole compound for resilient underfoot protection.

MIDSOLE

  • EVA midsole foam for durable cushioning.
  • Natural Ride System (NRS) design includes a more natural, foot-shaped last, zero millimeter heel to toe drop, and metatarsal-specific shapes in the outsole to assist in proper foot mechanics and allow for more natural foot movement.

UPPER

  • Air Mesh provides light, breathable coverage.
  • Heel Claw construction uses a snug fit around the heel for added support.
  • A-Wrap design holds feet securely around the midfoot and allows for a roomy toe-box.
  • Seamless Upper reduces irritation and provides next-to-foot comfort.
  • Support Insoles are 5mm-thick removable insoles designed for runners needing more traditional support and a molded arch.
  • Strengthen Insoles are 3mm-thick removable insoles made of A-bound material, with a flat platform designed to strengthen runners' feet.
  • Asymmetrical Lacing Design follows the shape of the foot for an improved fit and feel.
  • Drilex liner manages moisture for a dry and comfortable foot environment.
  • Strobel Last with the upper stitched to full length fabric for a comfortable underfoot feel.
