Good to know

  • The 12th version of the popular trail running shoe series, the Adrenaline ASR gives the runner a well-cushioned and stable ride with its reliable and robust underfoot platform. Traction over rugged terrain is much more effective because of a trail-optimized external layer.
  • The upper unit brings a secure and comfortable fit that’s reliable all throughout any activity. It makes use of high quality materials that prevent water from entering the shoe. The environment in which the foot rests remains dry and cool, even after longer periods of time.
  • The mid-sole unit has cushioning systems that are tuned to the individual needs of each runner. The foam even molds itself to the natural shape of the underfoot, so the platform becomes as comfortable as it can be. Stability is given by a tri-density unit that’s located in the mid-foot. This shoe’s mid-sole is comfortable and supportive.
  • Durable protection from wear and abrasion is afforded by an outsole unit that uses a reliable design that’s enhanced for the trails. Gripping lugs deliver high levels of traction and skid-resistance, making the shoe very capable of having surface control.

The Brooks Adrenaline ASR 12 has a standard running shoe length. It is available in sizes that adhere to the measurements that most runners are accustomed to. The forefoot, mid-foot and heel sections have a medium width, so this shoe can accommodate runners who have feet that are medium-sized. Its semi-curved shape welcomes the natural curvature of the human foot.


The HPR Plus is a high-abrasion-resistant material that’s placed in critical areas of the outsole. It serves as a shield that protects the rest of the sole unit from the potentially damaging effects of surface friction. It can even handle landing impact because of its durable form.

The HPR Green is a compound that’s chiefly put in the forefoot section of the Adrenaline ASR 12 and that of its latest version the Adrenaline ASR 14. Made with dispersed silica, this durable material gives high levels of traction and resistance to skidding, so each multi-surface traversal is more supported and unflinching to slippage.

The Stable Pod Configuration is the pattern made for the mid-sole/outsole unit. It was made to lead the foot towards a better step and a more balanced stance from the heel to the forefoot.


The BioMoGo DNA is a mix of the BioMoGo and DNA technologies that make the mid-sole as comfortable as possible for each runner. This unit actually conforms itself to the curvature of the runner’s underfoot, giving support and full-length cushioning.

The Progressive Diagonal Rollbar or RDRB is a unit that runs from the medial heel to the medial forefoot section. It’s made from a tri-density BioMoGo that efficiently reduces the rate of over-pronation without being too stiff.

The DRB Accel is a mid-foot unit made from thermoplastic polyurethane. It delivers mid-foot support and torsional rigidity, thus making the ride much smoother.

The Omega Flex and Flextra mid-sole components deliver flexibility to the mid-sole platform. It allows the mid-sole to move naturally with the foot, while also retaining its supportive and cushioning purposes.


The Element Mesh is a soft external fabric that is able to wick off moisture. It’s also breathable, so it provides ventilation to the foot of the wearer. It has been treated with DWR or a durable water-repellent coating.

The Element Lining is the inner sleeve of this running shoe. It’s a smooth fabric that is also able to stave off moisture while keeping the foot comfortable. The Hydrophobic Foam Package greatly adds water-resistance to the upper unit, keeping the interior as dry as possible.

The Profile Sock Liner is an added layer to the upper that makes use of the BioMoGo technology. It delivers contoured support right next to the foot, so the platform is able to continually deliver a well-balanced ride to the wearer.
