Anta Zone 2 Heart Rate 90 "Heartbeat" — Lightweight Super-Trainer for Daily Aerobic Training
The Anta Zone 2 Heart Rate 90 "Heartbeat" (Style Code: 122625579-4) is an exceptionally lightweight, plateless super-trainer specifically engineered to bring premium race-day foam into daily aerobic training. At just 162g (Women's US 7), it ranks among the lightest high-stack daily trainers on the market.
🎨 Design Story
The "Heartbeat" edition features a striking white, red, and silver/gold palette inspired by cardiac rhythms and performance vitality. The design mirrors a minimalist, modern aesthetic reminiscent of high-end marathon shoes.
🔧 Construction
- Upper: Anta's proprietary AT-FIBER (AT50) mesh — thin, pliable, tissue-paper-like texture with a premium, secure wrap feel
- Deconstructed Build: Non-gusseted tongue and minimal heel foam with soft Achilles carriage and external plastic reinforcement to shed weight
- Midsole: Massive 35mm heel / 27mm forefoot stack (8mm drop) of unplated Nitro90 supercritical nitrogen-infused super foam
- Stability: Extended nylon shank embedded in the midfoot — no stiff carbon plate
- Outsole: Anti-Wear Rubber (AWR) for lightweight protection
⚡ Performance
Optimized for Zone 2 base building, recovery runs, and steady-state mileage. The full-length Nitro90 foam delivers over 90% energy return — bouncy, soft, and effortlessly nimble.
- ✅ Best for: runs under 60–90 minutes, easy days, aerobic base work
- ⚠️ Limitations: soft foam is inherently less stable for sharp cornering or severe overpronation; AWR outsole can slip on wet pavement
📏 Sizing Advice
- Fit: True to size (TTS) relative to Nike and Adidas
- Last: Narrower heel capture, snug midfoot, slightly tapered toe box
- Recommendation: Order your standard running size for narrow-to-normal feet. Go half size up if you have wide feet, high instep, or prefer extra toe-splay room for downhills
