Adidas Hyperboost Edge Launches a New PEBA-Class Foam at 45mm Stack for $200

What it is

The adidas Hyperboost Edge is adidas's March 2026 debut of the new Hyperboost Pro midsole foam, the brand's first serious PEBA-class formulation built to compete with Nike ZoomX and On Helion HF. The shoe is an unplated super-trainer with 45mm heel stack and 39mm forefoot stack (6mm drop), weighing 9 oz for US men's 9.5. The upper is Primeweave engineered mesh with overlay reinforcement. No carbon plate; the energy return comes entirely from the Hyperboost Pro foam.

Pricing: $200 US / £170 UK.

What's interesting

Hyperboost Pro is adidas's long-awaited PEBA competitor. RunRepeat's cut-in-half lab analysis confirmed the foam is a true PEBA formulation, not an EVA-PEBA blend like some competitors. Lab-measured energy return exceeds 80%, putting the Hyperboost Edge in the same class as Nike ZoomX and Asics FlyteFoam Turbo.

45mm stack at 9 oz is class-leading weight for a PEBA super-trainer. Tom's Guide measured the Hyperboost Edge as roughly 1-1.5 oz lighter than comparable max-cushion PEBA trainers (Saucony Endorphin Speed 4, On Cloudmonster 3 Hyper). For marathon training, the weight advantage compounds across tens of thousands of steps.

The unplated design is deliberate. Unlike carbon-plate racing shoes that force a specific gait, the Hyperboost Edge lets the runner's natural stride determine how energy is delivered. For daily training, easy runs, and long runs, the unplated architecture is more forgiving and less fatigue-inducing.

Believe in the Run called it the "super-trainer" that finally matches adidas's reputation, specifically praising the smooth heel-to-toe transition and the foam's responsiveness under both slow and fast paces.

The Primeweave upper uses recycled polyester yarn and has a reinforced toe box structure. For adidas, this is a step toward the premium performance uppers that Nike and Asics have offered for years.

What's missing or unverified

The Primeweave upper has overlay patches that Tom's Guide and Doctors of Running flagged as "not very breathable in hot conditions." For warm-weather runners, the shoe runs 2-3 degrees warmer than competing engineered-mesh alternatives.

The heel collar is stiff and tall, which multiple reviewers described as a "regular annoyance on the run." For runners with sensitive ankles or those sensitive to collar pressure, this is a real fit concern.

At $200, the Hyperboost Edge is in competitive pricing territory. The Saucony Endorphin Speed 4 at $170 and New Balance FuelCell SuperComp Trainer v3 at $180 offer similar spec sheets at lower price. Adidas's positioning depends on whether the Hyperboost Pro foam justifies the premium over established competitors.

First-generation foam durability is unknown. Long-term PEBA degradation typically appears after 300-400 miles; no reviewer has tested the Hyperboost Edge across a full training cycle yet.

Outsole rubber coverage is limited to high-wear zones. Mileage before outsole exposure varies by stride; Doctors of Running expected 300-400 miles of useful life.

Who it's for

adidas ecosystem loyalists ready to test the new Hyperboost Pro foam. Marathon and half-marathon trainers who prioritize daily-training responsiveness. Runners who want an unplated super-trainer that lets natural gait determine pace.

Not for: hot-weather runners (the Primeweave upper is warm), runners sensitive to heel-collar pressure, or short-distance racers (carbon-plate racers are the right tier).

Ride character and training use

Reviewers agree the Hyperboost Edge feels best on easy and steady-effort days. Run to the Finish explicitly framed it as "Big Stack, Bold Look, Better Suited for Easy Days Than Fast Ones", meaning the unplated PEBA foam excels when the runner is not trying to push pace. For tempo runs above 7-minute-mile pace, a carbon-plate racer like the Adizero Adios Pro or Saucony Endorphin Elite delivers more specific energy return at those efforts.

The 6mm heel-to-toe drop is modest by max-cushion standards. Most 45mm-stack competitors use 8-10mm drops to encourage forward rolling; the Hyperboost Edge's 6mm keeps the runner closer to a natural ground feel, which some runners prefer and others find less efficient over long distances.

Verdict

The adidas Hyperboost Edge is adidas's best running shoe in years. Hyperboost Pro foam is a legitimate PEBA-class introduction, and the 9 oz weight at 45mm stack is class-leading. Against the Saucony Endorphin Speed 4 and On Cloudmonster 3 Hyper, the adidas wins on weight and brand-introduction foam; it loses on upper breathability. For adidas loyalists and runners looking for a daily super-trainer, this is the right pick.
