Trainer Roundup — 11 September 2026

It’s been a genuinely busy fortnight for shoe releases — eight significant launches landed in the last two weeks alone, from a first-ever carbon plate at Merrell to a full foam overhaul at Mizuno. Here’s the trainer roundup: what’s new, what’s actually changed under the hood, and what’s still to come before the year’s out.

Recently released

Merrell MTL SpeedArc Peak — US $290 (UK price TBC)

305g · 6mm drop

Merrell’s first carbon-plated trail racer arrives with a three-layer “SpeedArc” midsole: a full-length carbon plate sandwiched between a soft top layer of PEBA foam and a firmer, more durable base layer. It’s a direct shot across the bow of Hoka’s Tecton X on technical terrain.

ASICS Sonicblast 2 — £170 (US $190)

242g (men’s) · 8mm drop · 38–46mm stack

A significant update: 14g lighter than the original, with a redesigned “forked” plate that lets more FF Turbo+ foam extend into a new forefoot “Trampoline Pod” for extra pop off the toe.

Nike Pegasus Plus 2 — US $165

270g (men’s) · 10mm drop · 38mm heel / 28mm forefoot

The big change here is a forefoot Air Zoom unit — the first time this line has had one — which Nike says gives 18% more energy return than the original Pegasus Plus. It nudges the shoe from “everyday trainer” territory toward something you’d reach for on a tempo day.

Salomon S/LAB Genesis 2 — US $150

281g · 8mm drop · 33.5mm heel / 25.5mm forefoot

A stability-focused update for technical trail: a redesigned “activeCHASSIS” and wider midsole base pair with a revised, grippier tread for rougher ground.

New Balance SC Elite v6 — US $275

190g (men’s) · 8mm drop · 40mm heel / 32mm forefoot

New Balance has swapped in a new “Infinion” supercritical midsole compound in place of the old FuelCell foam, describing it as more resilient and race-ready — a real step up from the v5, which rode more like a lightweight trainer than a genuine racer.

Brooks Hyperion Elite 6 — US $275

192g (men’s) · 7mm drop · 40mm heel / 33mm forefoot

Brooks’ marathon super shoe gets a wider midfoot — addressing the narrow-fit complaints that dogged the v5 — paired with a more aggressive rocker geometry.

Mizuno Wave Rider 30 — US $150

~266g (men’s) · 8mm drop · 42.5mm heel / 34.5mm forefoot

A genuine departure for the line: a softer supercritical “Enerzy NXT” foam replaces the old, firmer compound, and the signature Wave plate is now full-length rather than partial. Expect a much plusher ride than Wave Riders past.

ASICS GT-2000 15 — US $150

252g · 8mm drop · 37mm heel / 29mm forefoot

Asics’ stability workhorse adds 2mm more foam over the 14 for extra cushioning, while keeping the FF Blast Max midsole and 3D Guidance System support underfoot.

Also released this window, with specs still filtering through: Saucony Cohesion 19 and Endorphin Elite 3, Puma Velocity Nitro 5 and Deviate Pure Nitro, Altra Olympus 7 and Vanish Carbon 3/Pulse, On Cloudboom Strike 2, Hoka Clifton 11 (upper refresh only) and Arahi 9, and the ASICS Blazeblast — a road-to-trail hybrid at $150 / 252g / 8mm drop.
