Zone2 verdict
The Adrenaline GTS 25 is a structured-support daily road shoe, not a medical correction device. Brooks combines GuideRails with balanced nitrogen-infused cushioning, a 10mm drop and a secure mesh upper. That makes it most relevant to runners and walkers who already know they prefer the way GuideRails limits excess movement. It is less compelling for somebody seeking a light racer, a low-drop platform or a neutral shoe without an added guidance system. Zone2 has not run-tested this model, so the verdict is based on its current UK specification.
Best suited to
- Runners who have previously liked Brooks GuideRails
- Daily road mileage and walking where a structured platform is preferred
- A dependable support-shoe slot with several width choices
Look elsewhere if
- You want a neutral platform without GuideRails
- Low weight and race-day efficiency are the main priorities
- You run mostly on mud, fell or technical trail

Construction: what matters
The defining component is the GuideRails system, which Brooks says helps keep excess movement in check while allowing the body to follow its natural path. The brand also added nitrogen-infused cushioning in the heel and forefoot and uses an engineered mesh upper intended to balance stretch, breathability and structure. These features explain the product category; they do not prove injury prevention or establish that more guidance is better for every runner.
Ride intent and practical role
The 300.5g men’s sample and 10mm drop put the Adrenaline firmly in everyday trainer territory. Its specification favours repeatable road mileage, walking and longer steady sessions over a minimal or race-specific feel. The cushioning is labelled balanced rather than maximum. A runner comparing support shoes should pay as much attention to how the sidewalls and rails feel around the foot as to headline foam language, because an unobtrusive system for one person can feel unnecessarily controlling to another.
The sensible use case is daily road running, recovery-paced mileage, long steady runs and substantial walking. It is not waterproof and the road outsole is not a substitute for trail lugs. As part of a rotation, it covers the same broad daily role as the Ghost 18 but with a different guidance proposition. Buying both only makes sense if you deliberately want to compare those rides; most runners need one daily option plus a genuinely different trail, speed or race shoe.
Fit and width
Brooks’ width range is useful, especially for runners who otherwise compensate for forefoot width by sizing up. Start from measured foot length and width, then check heel movement, toe clearance and pressure along the inside and outside edges. The secure upper is a manufacturer feature, not a promise of universal lockdown. Orthotic users should take the actual device to the fitting and confirm volume and heel security rather than assuming a support-labelled shoe automatically works with it.
What this review cannot establish
Zone2 has not retained a test pair, measured deformation, logged mileage or run a wet-surface protocol. We therefore do not assign a comfort, grip or durability score. GuideRails should not be described as correcting pronation or preventing injury: footwear preference, training load, previous experience and fit all matter. Product pricing and colour availability change quickly, so check the linked UK listing. Pain that alters gait or persists should prompt appropriate clinical advice, not another speculative shoe purchase.
What to compare it with
Choose the Adrenaline GTS 25 instead of the Ghost 18 when GuideRails is a feature you actively want. Compare it with the ASICS GEL-KAYANO 32 or Saucony Guide 19 when evaluating different approaches to adaptive or sidewall-based guidance. None is automatically the ‘most supportive’ for an individual; the best comparison is the one you can fit and run in safely.
