Technology :

• DRB Accel™ To promote natural movement between the heel and forefoot, Brooks developed the DRB Accel™. This component utilizes varying durometers of thermoplastics which provide the torsional midfoot support runners need. 

• HPR is a super-durable rubber compound developed specifically by Brooks. This rubber provides greater resistance to high wear areas of the outsole, such as the heel, increasing the life of the shoe. 

•  HydroFlow®-Brooks' patented, silicon-based system is the most unique and effective cushioning system ever applied to a running shoe. Its fluid-filled center chamber dampens shock at impact and dynamically disperses fluid at a controlled rate around the heel cushioning, stabilizing and rebounding on every stride. Plus, it's engineered to never wear out.

• The Diagonal Rollbar - When the foot comes in contact with the ground, it has a natural tendency to pronate. To help control this movement, we developed the Diagonal Rollbar™. This patented, wedge-shaped piece of high density foam is positioned on the medial side of the midsole to reduce the rate and speed of pronation.
