Short answer
The Brooks Adrenaline GTS 24 solidifies its benchmark status in the stability daily trainer category, introducing a revised upper architecture and updated midsole geometry that deliver a highly snug fit through the midfoot and a slightly low-volume toe box. True to size, but slightly small for some; consider half size up if wide feet.

Fit Notes
- ASICS Gel Kayano 32
- The Kayano 32 features a straighter last and a wider, more spacious toe box compared to the Adrenaline. By comparison, the Adrenaline GTS 24 has a slimmer midfoot and lower vertical volume. Runners who prefer a relaxed forefoot or require additional space should opt for a Wide (2E) variant or size up a half size to prevent constriction, while those with narrow to standard feet can remain at true length.
- Saucony Guide 18
- Saucony's Guide 18 utilizes CenterPath technology, which provides a broader base and a generous toe box that allows natural toe splay. Due to the firmer ride and lower vertical toe box volume of the Adrenaline GTS 24, a half-size increase to a US 10.5 (EU 44.5) is highly recommended to avoid distal toe compression against the shallow upper ceiling.
- Brooks Ghost 16
- While sharing a similar DNA Loft v3 platform, the neutral Ghost 16 features a more pliable upper and lacks the rigid, cup-like GuideRails structure. The Adrenaline GTS 24 feels noticeably shorter and tighter due to its rearfoot 'bucket seat' design. Therefore, a half-size increase is a common necessity for runners transitioning between these two models to maintain an identical length profile.
- Nike Pegasus 41
- The Nike Pegasus series is notoriously narrow through the midfoot and heel, featuring a tight toe box. The Adrenaline standard width is slightly wider than the standard Pegasus. This introduces an important compensation factor: if you normally size up in the narrow Pegasus line *just to secure extra width*, you should return to your true length (US 10.0 / EU 44) in the Adrenaline GTS 24, as it offers superior width options (2E/4E) to find lateral relief without creating excess length.
Sizing FAQ
Does the Brooks Adrenaline GTS 24 run true to size?
While industry specifications designate the Brooks Adrenaline GTS 24 as true to size (TTS), user experiences and clinical evaluations indicate a clear tendency to run slightly short and narrow. The physical length of the last is accurate, but the internal volume is restricted by two design elements: a low-profile vertical toe box height and a snug, highly structured midfoot wrap. Additionally, the dense materials used in the Gore-Tex (GTX) version further compress the internal space. For runners who prefer a thumb’s width of clearance at the toes or who experience normal foot swelling during daily mileage, sizing up a half size from their standard casual shoe size—or transitioning from roomier neutral models like the Ghost 16—is strongly recommended to achieve an optimal fit.
Is the Brooks Adrenaline GTS 24 good for wide feet?
The Brooks Adrenaline GTS 24 is an exceptional option for runners with wide feet, but only when utilizing the brand’s dedicated wide width selections. The standard 'D' (men's) and 'B' (women's) widths feature a tapered forefoot and a highly locked-down midfoot that can cause discomfort, pinching, or blisters for wider foot profiles. However, because Brooks manufactures this model in comprehensive Wide (2E/D) and Extra Wide (4E/2E) configurations, runners with wide feet can easily find an accommodating platform. Selecting these wider options provides the necessary volume to allow proper toe splay and relaxes the midfoot wrap without compromising the rearfoot security and heel lockdown provided by the rigid heel cup.
How is the arch support on the Brooks Adrenaline GTS 24?
The arch support of the Brooks Adrenaline GTS 24 is highly robust and adaptive, though it leans toward a firm, structured feel rather than a soft, contouring fit. Rather than relying on static arch cookies, the shoe uses the GuideRails system to cradle the rearfoot and midfoot, keeping the calcaneus and ankle aligned in a neutral plane. The medial rail in the GTS 24 is firmer and more substantial than in previous versions, which enhances pronation control but also increases direct pressure against the arch. While this setup is highly effective for moderate overpronators, it can cause friction or hot spots for runners with sensitive or flat arches. Because the DNA Loft v3 midsole is designed to maintain its structural firmness over hundreds of miles and does not stretch or break in significantly, runners should ensure an immediate comfortable fit out of the box.
