Built for the miles that build you.

The Anta Zone 2 Heart Rate 90 is engineered explicitly for Zone 2 endurance training — the 60%–70% max heart rate zone where aerobic base is built, daily mileage stacks up, and real running fitness is forged. Unplated, uncompromising, and loaded with ANTA's top-tier Nitroedge 90 foam, this is one of the highest-value super trainers on the market for neutral runners who want a daily cruiser that takes the harshness out of road running.

The "Fluorescent Dazzling Orange" colorway (Style Code: 112635579-2) brings bold Orange/Blue/White energy to every session — whether it's a recovery jog at dawn or an up-tempo block in the afternoon.

Sizing

Unlike older Chinese running models, the Zone 2 aligns accurately with Western standards. Order true to size (TTS) relative to your Nike, ASICS, or Brooks running shoes. The midfoot is average width with a comfortable, roomy toe box.

Midsole: Nitroedge 90 Foam

The defining feature is a massive, full-length stack of Nitroedge 90 — ANTA's top-tier supercritical racing compound, formulated to be lighter and more explosive than standard daily trainer foams. It compresses deeply and returns a highly energetic, fun bounce underfoot that makes every mile feel effortless.

Stability: Unplated Layout + Midfoot Torsion Shank

Instead of a rigid carbon plate that can feel stiff and clunky at recovery paces, the Zone 2 uses an open, unplated foam layout paired with a localized midfoot torsion shank. Your foot flexes naturally through the gait cycle while receiving just enough structural support to stay controlled on long runs.

Geometry: Aggressive Forefoot Rocker

The tooling mimics elite marathon racing geometry. As your weight shifts forward, the curved forefoot rocker springs you smoothly into the next stride — reducing calf strain and promoting efficient turnover across daily mileage.

Upper: AT-Fiber Mesh

A tightly woven AT-Fiber mesh upper wraps the foot like a supportive sock with highly secure midfoot lockdown — no internal sliding, no hot spots. The material feels incredibly premium and runs slightly warm, making it ideal for cool-weather runs and cozy on cold mornings.

Outsole: Anti-Wear Rubber (AWR)

Textured AWR rubber is laid over high-impact zones to protect the Nitroedge foam and deliver optimal traction on dry asphalt and bike paths. Best suited for dry conditions — users note reduced grip on slick, rain-soaked roads.

Who Is This For?

• Neutral runners building aerobic base through Zone 2 training
• Runners seeking a lightweight daily cruiser for recovery runs and steady miles
• Up-tempo training blocks where a plated shoe feels like overkill
• Anyone who wants elite foam energy without the stiffness of a carbon plate
