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.

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

E-Fusion™ : e-0™ is a new engineered outsole material that delivers unsurpassed skid and abrasion resistance compared to traditional outsole materials, e-1™ is a new compound, engineered to dampen and dissipate shock upon heel impact. e-2™ is a highly resilient compound with a superior spring rate. Positioned into the forefoot, the result is a toe-off that's truly explosive.

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

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.

PDRB™ : Progressive Diagonal Rollbar : Dual Density Post is bio-mechanically engineered to allow progressive pronation control.

Pod Tec® : Podular Technology : Midsole/Outsole a configurations system in the mid/out sole to enables the shoe to bend and flex.

HPR™ : High Performance Rubber : A super-durable rubber compound provides greater resistance to high wear areas of the outsole.

S257™ : Substance 257 : Brooks unique midsole compound is formulated to resist com-pression and rebound more quickly after impact.
