BioMoGo™, Midsole : 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.

Blown Rubber, Forefoot : Is lightweight and flexible. It provides added cushioning while maintaining durability and a smooth ride.

Caterpillar Crash Pad : Segmented impact absportion pad crash pad that customizes to the runners lay down, which offers the right amount of cushioning and stability for a smooth transition from heel-to-toe.

Traditional strobel lasts use a thin cloth material, while newer variations use a thin sheet of EVA for a more cushioned feel.

DNA™, Forefoot n Rearfoot : Provides a customized ride for runners of all sizes and speeds, dispersing impact and providing ideal comfort and protection as the pace changes.

DRB™, Medial Post : Diagonal Roll Bar : High density foam positioned on the medial side of the midsole to reduce pronation.
