BioMoGo® : Fully biodegradable midsole foam for footwear. Once a pair of Brooks shoes with BioMoGo has reached an enclosed landfill, it will begin to biodegrade. In roughly 20 years the midsoles will be completely converted by common soil microbes into useful humus and nutrients. That’s about 50 times faster than a standard midsole degradation. MoGo® : Brooks claims, MoGo offers 40 percent more cushioning and gives a runner 22 percent more return of energy - the "spring" in one's step - than Brooks' former midsole. Substance 257. MoGo not only represents a giant leap forward in midsole material performance for Brooks, it also entails an evolved method of production. Compression Molded Preform (CMP) is an efficient, precise production process in which, rather than being cut out of large sheets of material in the traditional method, midsoles are cast in individual molds, resulting in 50% less waste. The CMP process also increases consistency by an incredible 200%. Less variability between midsoles ensures that runners can count on enjoying the same feel pair after pair.

BioMoGo® Profile Sockliner : Placed underfoot and is made of for cushioning and forms a contoured support sensation.

Caterpillar Crash Pad : Heel impact absportion pad to further soften the ride, while improving the heel-to-toe transition.

Cushsole S257™ Last : Provide a softer underfoot feel.

DRB Accel™ : To promote natural movement and provide torsional midfoot support.

Element™ : Upper and Inner Lining : A microfiber construction that provides strong protection against the elements in a light and quiet fabric. Element™ maintains full breathability and durable comfort.

Forefoot HydroFlow® : Located under where the metatarsal head region of the foot rests in the shoe, used to attenuate shock and dampen forces : HydroFlow® : Liquid silicon-based system cushioning system chamber dampens shock at impact and dynamically disperses fluid at a controlled rate around the heel cushioning, stabilizing and rebounding on every stride.

HydroFlow® ST : Located in the heel and is cushioning device which consists of a chamber filled with viscous fluid. Hydroflow ST is designed toLoacted in the heel to attenuate shock, dampen impact forces and provide addational heel stability : HydroFlow® : Liquid silicon-based system cushioning system chamber dampens shock at impact and dynamically disperses fluid at a controlled rate around the heel cushioning, stabilizing and rebounding on every stride.

HPR™ Plus : High Performance Rubber Plus : A higher durability, abrasion-resistant rubber outsole compound that wears longer.

Internal Support Saddle : Located in the midfoot with the purpose of providing a more secure midfoot fit.

Stable Pod Configuration : A midsole and outsole design engineered to set the foot up for an balanced position for an efficient heel to toe-off motion. Providing stability and responsiveness.
