Good to know
- This latest version of the Brooks Adrenaline ASR is lighter than its predecessor. For the men’s shoe, the size was reduced from 315g to 309g. For the women’s version, the 261g weight was reduced to 249.5g. With this weight reduction, runners are given more freedom of movement without feeling weighed down.
- From a standard stability running shoe, the support was upgraded to motion control. This type of shoe is best for runners who overpronate. The level of support provided by this shoe helps in averting injury or pain, especially on the knees. Overpronating runners are offered the maximum foot support as they run on the trail with the Adrenaline ASR 14.
- A proprietary technology called the DRB Accel was introduced to the midfoot of the shoe. The DRB Accel is a thermoplastic polyurethane unit that aids in balancing the support and torsional rigidity of the shoe.
- The design of the upper has also been updated with changes made on the overlays. The water-resistant mesh material is retained, but a new web-like saddle is added to enhance the fit of the shoe through the lacing system.
- The tread of the shoe was redesigned to offer better traction, grip, and flexibility to runners. Particularly, the indentations were deepened and the rubber on the outsole was segmented so the shoe can easily move with the runner’s movements.
The Brooks Adrenaline ASR 14 comes in standard shoe measurements. Runners will be able to get a pair using their usual running shoe sizes. The width is similar. The shoe is available in regular widths for both males and females.
Key areas of the outsole are made up of an abrasion-resistant rubber known as the Brooks HPR Plus. This material is tough, adding more durability to areas that commonly give in when running in trail shoes. It also enhances the grip and traction of the shoe, without sacrificing flexibility.
Another rubber material that Brooks has partnered with the HPR Plus is the blown rubber. Other areas of the outsole are made with this material. Compared with the HPR Plus, this rubber material is not as robust, but it gives more flexibility to the sections of the foot that need it the most. On top of that, it also helps to provide a more responsive ride to runners.
Brook’s Stable Pod Configuration was also introduced to the outsole. With some components of this technology found on the midsole, it sets the foot up to a more efficient position which optimizes the movements from heel strike to toe-off. Ultimately, this is one of the main features of the shoe that allows it to give maximum stability.
Lastly, the Flextra technology was added as well. Flextra is a special system in the anterior part of the outsole. This system complements the other features that enable flexibility. It offers varying degrees of support resulting in a more fine-tuned level of malleability.
One of the main technologies that Brooks has added to the midsole of this shoe is the BioMoGo DNA. This is the same midsole technology found in the popular trail running shoe, Brooks Caldera 3. Breaking it down, with standard Brooks DNA, the cushioning material is made of a special Non-Newtonian fluid. Amazingly, this fluid is turned into a gel-type insert that adjusts its viscosity depending on the amount of force it receives. So, if runners put a higher amount of force on the shoe, the gel becomes stiffer.
With BioMoGo, this piece of midsole material is Brooks’ environmentally friendly creation. Unlike EVA midsoles, this foam is made out of recycled materials and it degrades naturally post its effective lifespan. Combining this with the DNA technology, the BioMoGo DNA replaces the gel inserts. By eliminating the insert cutouts, this technology is safer for the environment, yet it still provides responsive cushioning.
Within the midsole is the Progressive Diagonal Rollbar or the PDRB. This component is seen from the outside of the shoe and it’s outlined by a different color. This internal midsole structure greatly helps with pronation. It’s a stability feature inhibits the foot from turning, while enhancing the transition from the midstance to propulsion.
Another component in the midsole that prevents overpronation from happening is the DRB Accel. It can be seen in the midfoot area and is a component that’s made of thermoplastics with varying levels of sturdiness. This unit provides torsional rigidity and it balances the support received by the dorsal part of the foot.
The design of the platform leans more towards optimal flexibility and cushioning through combining two technologies. The first one is the full-length Crash Pad feature. These are segmented structures that provide next-level cushioning, stability and smoothness of the running transition. These segments are able to move easily and freely because of another feature that heightens flexibility – the Omega Flex Grooves.
A profile sock liner was also introduced to the inside of the shoe. This sock liner is made of BioMoGo foam and is contoured according to the natural shape of the underfoot. It provides extra cushioning and is supplementing the already-comfortable in-shoe experience runners get.
The upper of the Brooks Adrenaline ASR 14 is made up of a material called Element Mesh. This type of mesh has been treated with a durable water repellent to combat water or moisture from getting into the shoe. This is a very nifty shoe feature when running on wet terrain or when accidentally stepping into a puddle.
To further secure the fit of the shoe, Brooks enhanced the design of the synthetic overlays. These structures are now formed into a cage-like design that lightly locks the midfoot in place while also providing more structure to the shoe. The secure fit this feature brings is further augmented with the adjustable saddle construction which really gives runners a personalized and dependable fit.
The Element Mesh upper is partnered with a lining inside the shoe that is made up of a similar element material. Brooks refers to it as Element Linings, and its primary goal is to aid in moisture transfer within the shoe while also providing a comfortable in-shoe feel.
