Brooks Adrenaline GTS 24: Specification Analysis (Not Yet Tested)

The published specification

What a foot and ankle surgeon reads into these numbers

The Adrenaline is the shoe most often handed to someone told they overpronate. What Brooks actually builds is a firmer midsole (44.1 Asker C, the firmest in this batch), a reinforced heel counter, and GuideRails — raised foam walls either side of the heel that limit how far the rearfoot can roll rather than propping the arch up from underneath.

That distinction matters. A medial post pushes up under the arch and can be uncomfortable over a rigid or already-supported foot. A guidance system that works at the heel tends to be better tolerated alongside a custom orthotic, because the two are not fighting for the same space. It is one reason this family is a common recommendation for posterior tibial tendon dysfunction and adult-acquired flatfoot.

The 13.5 mm drop is doing quiet work too: the higher the heel sits relative to the forefoot, the less the Achilles and plantar fascia are asked to lengthen at push-off.

Orthotic fit

Brooks states the insole is removable, and a heel-based guidance system generally coexists better with a custom device than an aggressive medial post does. What decides the question is internal volume and heel-counter depth once the stock insole is out — which is exactly what our Orthotic Volume Rating measures and exactly what a specification cannot tell you. This shoe has no OVR yet. If you wear a custom device and you are choosing today, buy from somewhere with a returns policy and try the device in the shoe.

Questions people ask about the Adrenaline GTS 24

What is the Brooks Adrenaline GTS 24 good for?

Everyday running and walking for a foot that rolls inward. It is Brooks’ mainstream stability trainer, and its support comes from GuideRails — firmer walls either side of the heel that limit excess movement — rather than a hard post jammed under the arch. Four widths and a removable insole make it one of the more orthotic-tolerant stability shoes on sale.

Is the Brooks Adrenaline GTS 24 good for walking?

The specification suits walking well: a high heel, a cushioned but not unstable platform, GuideRails to limit rearfoot movement, and fittings up to X-Wide. It is a running shoe, so the outsole is built for forward motion rather than lateral work. What we cannot tell you yet is how the midsole holds up over the mileage a daily walker puts in — that is a wear-test question, and this pair has not been through one.

What is the drop on the Brooks Adrenaline GTS 24?

Brooks publishes 12 mm; the independent lab figure on this page is 13.5 mm. Either way it is one of the highest-drop mainstream trainers still on sale, which is a deliberate design choice rather than a defect. Both numbers and both sources are in the table above.

Do podiatrists recommend the Brooks Adrenaline GTS?

The Adrenaline is the stability shoe most often named in clinic after the Ghost, and usually for a defensible reason: GuideRails guide the rearfoot and knee instead of forcing the arch off a hard post, and it comes in four widths with an insole that lifts out. The number worth knowing is the drop — measured at 13.5 mm, this is a high heel. For Achilles tendinopathy or a tight calf that is frequently the point; for someone being moved deliberately toward a lower drop it is the wrong shoe, and the published 12 mm understates by how much. Podiatrist Tested has not tested this pair, so there is no score and no seal here. Whether the GuideRails still hold under a heavy, collapsing foot is a bench question.

Other shoes we have looked at

Drop is the figure that decides how load splits between your heel and your forefoot, so it is the fastest way to tell these apart. Where a figure was independently measured rather than taken from the brand, it says so — and on several of these the two disagree.

Adrenaline or Ghost? We put the Adrenaline GTS 24 and the Ghost 17 side by side on every measured figure — the real differences are drop and firmness, not width. Read the comparison.

Adrenaline or Kayano? Compared on every measured figure against the ASICS Gel-Kayano 32: near-identical heel height and toe box, but 5.1 mm less forefoot. Read the comparison.
