Li-Ning's Aerus line has been the most influential and the most polarising shoe story in badminton. The 2010 original introduced supercritical foam to the sport — a stack of springy bounce that felt unlike anything Yonex or Victor were making. The 2020 II refined the formula. Both versions had the same problem: the foam was lively, but the chassis underneath did not always control where it bounced. III Pro is the version that finally fixes that — same airy, energetic foam, now wrapped in a stability cage that keeps the shoe pointed where you push it.
What III Pro changes
- Foam
- Updated supercritical TPEE — same character as II, more consistent rebound across temperature.
- Cage
- Reinforced TPU lateral cage — first Aerus generation that fully arrests sideways foam squish.
- Outsole
- Family-resemblance Aerus pattern with refined directional grip zones.
- Colourways
- 5 options including Cotton Candy, Year of Snake, Artist, Warning, Dark Elf.
Aerus III Pro vs Yonex shoe family
| Decision point | Aerus III Pro | 65 Z4 | Aerus Z2 |
|---|---|---|---|
| Foam character | Springy / lively | Damped | Damped, low stack |
| Stability | Newly improved | Strong | Adequate |
| Speed | Medium-fast | Medium-fast | Very fast |
| Cushion stack | High | Medium-high | Low |
Buying call
Buy if you want lively foam with finally-fixed stability. Skip if you specifically prefer flat-foam ground feel.
- Best Aerus version Li-Ning has shipped.
- Wide colourway range — uncommon for serious court shoes.
- Pair with sturdy lateral lacing for additional lockdown.
Why supercritical foam was always a partial solution
Supercritical foam — gas-injected polymer that creates a uniform microcellular structure — is genuinely better than traditional EVA on bounce-back and weight. That is why Aerus changed the conversation when it launched. The catch was that the foam, by itself, did not control where the bounce went. On a hard lateral lunge, the foam compressed sideways before it returned upward, which produced a slightly drifty feel. Pros adapted; amateur players sometimes did not. III Pro adds the structural cage that keeps the foam compressing in the right direction.
What the new TPU cage actually does
On III Pro, the lateral TPU panels extend further along the midfoot than on II, and they tie into a redesigned heel cup that locks the foot more decisively. The result: when you push laterally, the foam compresses downward more than sideways. You still feel the springy character because the foam is unchanged, but the energy returns in the direction you intended. On a quick split-step recovery, this difference is felt immediately. On a deep lunge, it shows up as faster recovery.
Cushion vs ground feel
Aerus III Pro sits in the cushion-rich camp. The stack is taller than Aerus Z2 and noticeably above 65 Z4. If you prefer flat ground feel — short stack, immediate floor contact — III Pro is not for you. If you want a shoe that absorbs landing impact while still being responsive on push-off, this is the most refined version of that profile available right now. Players returning from ankle, knee, or heel issues will benefit from the cushion.
Width, fit, and Asian last
Like most Li-Ning shoes, III Pro runs an Asian last — narrower forefoot than European or Yonex equivalents, with a snug heel cup. Players with wide feet should size up half a size or test in person before buying. The seamless upper helps reduce hot spots on standard-width feet. Heel lock is excellent thanks to the reinforced TPU.
Who should buy it
Buy Aerus III Pro if you want springy supercritical foam with stability that finally matches its energy, your current shoe is an Aerus II or Comfort Z3, and you play all-court badminton with significant lateral movement. Skip if you specifically prefer flat foam (Aerus Z2), need maximum cushioning above all (Comfort Z3), or have wide feet that do not adapt to Asian lasts. The III Pro is the most refined Aerus generation yet — and arguably the best Li-Ning shoe of the past five years.
