HydroFlow® – Dynamic viscous fluid units for heel and forefoot
enhance midsole cushioning—attenuating shock with industry
leading dampening and comfort.

BioMoGo – We’ve taken the long-lasting cushioning of our
MoGo midsole and made it more environmentally friendly. How,
you ask? By adding a non-toxic, natural additive to the MoGo
compound that encourages anaerobic microbes to munch away
once it hits an active, enclosed landfill.

Diagonal Rollbar (DRB®) – A high-density post at the medial arch
is engineered for pronation control and creates a smoother transition
from the midstance phase into the propulsion phase.

DRB® Accel – Enhances tunable torsion of the midfoot. Shank-like
thermoplastic devices vary from single units of a set modulus, to
dual-unit versions of varied modulus (tuned with higher stiffness
for medial support, the lateral side less stiff to smooth the ride).

Outsole

• HPR Green
• Forefoot Stable Pod Construction
• Contact Rubber Forefoot

HPR Green – This durable and long-wearing outsole compound
is made with dispersed silica, resulting in premium wet-dry traction
for excellent skid-resistance and a more environmentally friendly
composition.

Engineered Stable Pod Configuration – Midsole and outsole
components are engineered to set the foot in an efficient, balanced
position from heel strike to toe-off, offering maximum stability and
responsiveness.
