Brooks Adrenaline GTS 26 vs ASICS GT-2000 15

Structured support with just-right cushioning is how Brooks describes the Adrenaline GTS 26, its everyday road stability shoe for daily runs, long runs and walking. Support comes from GuideRails, which the brand says work with the cushioning to manage excess movement without a traditional medial post. Underfoot is DNA Loft v3, a nitrogen-infused foam that is also used in the neutral Ghost 18.

Replacing the Adrenaline GTS 25, this version keeps the support system, the cushioning and the 10 mm drop, and changes the upper: an engineered double-jacquard air mesh, a soft flat-knit tongue designed to reduce bulk, and a flat-knit collar with a heel loop for easier on and off. It weighs 306 g in a men's UK 8.5, with wide and extra-wide fits alongside the standard width. The Glycerin GTS 23 is the more cushioned GuideRails alternative.

Replacing the GT-2000 14, the GT-2000 15 is ASICS' mid-range stability trainer, which the brand describes as a versatile, lightweight daily shoe for a range of distances. ASICS positions it as the lighter, more nimble alternative to the Gel-Kayano 33, and it sits above the cheaper GT-1000 15.

Guidance comes from the 3D Guidance System, which uses the midsole's geometry to guide the foot from landing through toe-off, in place of the Kayano's FluidSupport. Updated FF Blast Max foam is paired with PureGEL, and a forefoot trampoline pod borrowed from the Blast series is a feature the Kayano lacks. A new engineered woven upper completes the update, which ASICS says is lighter and taller than before. It weighs 252 g in a men's US 9 (UK 8.5), with an 8 mm drop, and comes in standard, wide and extra-wide fittings plus a GORE-TEX version.
