This just happened from a run in Transcend a couple weeks ago since I loosen the laces for casual wear and thought it would be fine for 6 miles – nope, blood blister on my medial forefoot from a shoe with 200+ miles without issue. In addition, Brooks is determined to prevent knee and hip pain by guiding foot motion, offering holistic support for the runner.

The way the guide rail works is that it initially provides extra support for when your ankle over-pronates (rolls inwards), and pushes your stride to a neutral position.Fans will also notice different shoelaces. The laces in the 19 were flat with a slight bit of stretch, but the laces threaded through the 20 are tubular and noticeably stretchier—they’re the same laces our testers loved in the Brooks Ghost 12 review.

Reflective patches atop the posterior heel and running along the lateral toe alert drivers in low light. Arch height is medium. Like the GTS 19, severe overpronators might struggle with the GTS 20 – the guide rail does not have the traditional support of previous versions of the adrenaline, but has more of a neutral fit that caters for the mild overpronator. DNA cushioning The Brooks Adrenaline GTS is one of our most popular running shoes at Run4It. They might just be one of the best stability running shoes ever made. Now on its 23rd edition, the latest Brooks Adrenaline features the most cushioned underfoot feel to date. This is because the Brooks Adrenaline GTS 23 has been updated with DNA LOFT v2. So I take the extra 20 seconds to snug up the laces on Adrenaline! They start to loosen slightly about 4.5 miles into a run, and the fit relaxes too much if avoid an extra tug-through at the start (if they’ve been loosened for all-day comfort). The padding on the heel collar has a corduroy-like texture but uses a silky fabric to minimize any rubbing that could occur with a coarser fabric. Despite the change, our testers didn’t notice any substantial difference between the two heel cups or padding.

There aren’t many differences between the 19th and 20th versions of the Adrenaline, so fans of the outgoing model will find a nearly identical experience in the new one. Last year, Brooks added the new guide rails to the Adrenaline. This year, they’ve updated them slightly. In a small alteration to the GTS 19, Brooks are now offering a co-bonded set- up, meaning the guide rail sits bonded into the midsole and runs along the lateral side of the shoe, from the heel, all the way along to the forefoot, offering extra support. If long runs of 10+ miles are your main training motif, yet you want a shoe that can also handle intervals, go with the Adrenaline GTS 20.
