Outsole

The outsole of the Adrenaline ASR 12 GTX is comprised of Brooks’ proprietary High-Performance Rubber (HPR) Plus. This rubber is abrasion resistant, even in areas that take the full brunt of impact during running. Rows of tightly packed lugs on the bottom of the shoe provide grip on rough and rocky trails. Brooks’ trademark Omni Flex Grooves in the forefoot give the outsole flexibility and also help the lugs increase their hold on loose rocks and slippery surfaces. The Omega Flex Grooves also work with an oversized segmented crash pad that runs from the heel to the midfoot. The crash pad provides more flexibility in the heel area which results in a smooth heel to toe transition. Runners commented that this outsole is much improved from the previous version.
Midsole

Midsole

Brooks’ patented BioMoGo DNA midsole rubber is the main component of the Adrenaline ASR 12 GTX’s midsole. This soft foam provides unique cushioning throughout the entire midsole, not just in the heel and forefoot. The foam has the ability to acclimatize to the runner’s weight, running style, and even the running surface. This feature provides customized cushioning with every step and also a very comfortable ride.

A Progressive Diagonal Rollbar in the midsole helps with overpronation issues. Tri-density foam acts as an internal post and adjusts the foot to a natural motion from heel to toe which prevents the ankle from rolling inwards during the gait cycle.

Durability

The Adrenaline ASR 12 GTX is solely made for extreme rugged terrain and the HPR Plus outsole abrasion-resistant meaning this shoe can stand up to a lot of misuse. Extended use on hard surfaces will wear down the outsole lugs prematurely, but that will not affect the durability of the shoe too much.

The Cascadia is also slightly heavier than the Adrenaline. One runner referred to the tread of the Adrenaline ASR 12 GTX as a “rock star” and estimated he could easily get 300 to 500 miles out of the shoe. For winter running, these shoes hold up very well and have no problem plowing through snow and slush.Material like Vinyl over the front part of this shoe works as a toe shiel d and assists in protecting the toe area. A similar material is put to use on the shoes back part and assists with the general development and durability.

The Adrenaline ASR 12 GTX is a fairly supportive shoe. A Progressive Diagonal Rollbar in the midsole helps prevent overpronation.
