1. Market Context
On the global running stage, Li-Ning is shedding its “budget shoe” reputation to become a legitimate heavyweight competitor to Western brands. While the Feidian line claims glory on the elite racing scene, the Red Hare series is the workhorse for the masses. With the Red Hare 9 Ultra, however, Li-Ning has pulled a shocker: they’ve turned a standard daily trainer into a max-cushion monster with absurd specs.
As a mid-pack runner (165cm, 57kg), approaching this shoe felt like a unique experiment. In Vietnam, it retails around 3,400,000 VND, making it aggressively priced for what’s on the spec sheet. I spent over a month putting this shoe through its paces on local asphalt—from cool early mornings to scorching afternoons—to determine if that 44mm stack is a genuine revolution or just marketing fluff.
2. Technical Specifications (Men’s US 8)
Before we dive into the ride, let’s look at the numbers:
- Weight: Approx. 225g–230g for a men’s US 8. This is a material science masterclass. Imagine a 4.5cm stack height that weighs as little as a lightweight racer.
- Stack Height: 44mm in the heel, 36mm in the forefoot. For perspective, that’s thicker than the Nike Alphafly or ASICS Superblast. This is literal clouds under your feet.
- Drop: 8mm. A sweet spot for smooth transitions across most foot strikes.
- Midsole: Full-length Boom foam (Lining’s high-end, proprietary PEBA material).
- Upper: Mono-yarn mesh, nearly translucent in some lighting.
- Outsole: GCR (Giga Control Rubber) with micro-grooves for traction.
3. The 44mm Boom Foam – The Illusion of Plushness
The heart of the Red Hare 9 Ultra is that massive slab of Boom foam. At 57kg, my first impression wasn’t the “mushy” soft of the ASICS Nimbus, but rather a “compressed resilience.” Li-Ning’s Boom is lightweight, high-density, and delivers exceptional energy return.
Standing on this 44mm platform, there is a total disconnect from the ground. Road vibration is virtually extinguished before it reaches my foot. However, since I don’t have the mass to bottom out the foam like an 80kg+ runner, the ride feels more like gliding on springs than sinking into a pillow. This is great news for anyone who hates that “trapped” feeling in overly soft shoes.
4. Upper Design and Weight Optimization
To hit 225g with such a massive midsole, Li-Ning had to strip back the upper. The mono-yarn mesh is extremely thin. In Vietnam’s hot, humid climate, this is a lifesaver. Even in high humidity, my feet stayed cool and breathable.
However, minimalism comes at a cost. The thin upper struggles to lock the foot down firmly against that 44mm platform. Even with a tight lace lockdown, I felt some lateral instability. The thin tongue also bites if you crank the laces too tight, causing discomfort across the instep.
5. Ride Analysis by Pace
Faster Paces (5:00/km – Mid-pack Tempo)
At 5:00/km, the Red Hare 9 Ultra reveals a fun personality. Thanks to the low weight, cadence feels natural. You don’t feel like you’re lugging a max-cushion shoe around. The Boom foam snaps back quickly, making for a surprisingly snappy turnover.
The issue arises in corners or on uneven pavement. With a 44mm stack, your center of gravity is high. At this pace, every footstrike demands focus from your stabilizer muscles. If you lose concentration, the shoe tends to want to roll. As a 57kg runner, there isn’t enough downward pressure to keep the platform grounded in sharp maneuvers, leading to a slight lack of confidence.
Slower Paces (≥7:00/km – Recovery)
This is the Red Hare 9 Ultra’s kingdom. At 7:00/km, when heart rate is low and relaxation is priority, the 44mm stack is pure bliss. I could log hours without a hint of joint fatigue. For the average runner who finds stiff shoes boring on recovery days, this shoe makes you want to get out the door. It shields my 57kg frame from the cumulative impact of a hard week of training.
6. Stability Analysis – The Achilles’ Heel
I need to address stability, as it is the most controversial aspect of this shoe. Is it unstable? Yes.
- Lack of Torsional Rigidity: There is no carbon or nylon plate. A 44mm stack of pure foam is prone to twisting.
- Extreme Height: High center of gravity equals low stability. A stray rock or uneven curb is enough to challenge your ankle.
- Footprint: Despite a widened base, the soft nature of PEBA foam means the edges aren’t firm enough to act as a solid anchor if you land off-center.
I rate the stability a 6/10. It requires decent ankle strength or, at the very least, a commitment to running on flat, predictable asphalt.
7. Performance Matrix
| Running Type | Pace ~5:00 | Pace ≥7:00 |
|---|---|---|
| Easy Run | 8/10 | 9/10 |
| Long Run | 9/10 (Straight lines) | 9/10 |
| Tempo Run | 7/10 | 6/10 |
| Interval | 5/10 | N/A |
| Recovery | 10/10 | 10/10 |
8. Foot Strike Compatibility
- Heel Striker: 7/10. The 44mm heel is plush, but if you over-stride or strike hard, watch out for the wobble.
- Midfoot Striker: 9/10. This is the safest and most efficient way to use the shoe.
- Forefoot Striker: 8/10. The 36mm forefoot offers great impact protection, though it may feel a bit like “overkill” for some.
9. Body Weight Sensitivity
This shoe favors lighter runners. At 57kg, the Boom foam doesn’t bottom out, maintaining its pop. If you are over 80kg, I suspect you’ll find this shoe too squishy and lacking the structural integrity required for stability.
10. Value Proposition
At a street price of ~3,400,000 VND, the value is undeniable. Achieving this level of PEBA (Boom) performance from Nike or ASICS would usually cost 4,000,000 to 5,000,000 VND. The GCR rubber is also durable; after 150km, the lugs are still sharp.
11. Final Verdict
The Li-Ning Red Hare 9 Ultra is a rebellious max-cushion trainer. It eschews traditional stability for pure, unadulterated comfort and low weight.
- Pros: Extremely plush 44mm stack; ultra-lightweight (225g); excellent breathability; high value for the tech.
- Cons: Poor stability; questionable lockdown from the thin upper; narrow toe box.
Overall Rating: 8.4 / 10.
If you’re a mid-pack runner looking for ultimate comfort on flat, long-distance road runs and have a 3 million VND budget, this shoe is peerless. If you run on rough terrain or have weak ankles, consider more stable options like the Nike Vomero Plus.

FAQ
Does the Li-Ning Red Hare 9 Ultra cause ankle rolling?
With a 44mm stack and no rigid plate, it can feel unstable on sharp turns or uneven surfaces. It works best for straight-line running with a midfoot strike.
How does the Red Hare 9 Ultra differ from the 9 Pro?
The Ultra uses a thicker 44mm Boom PEBA midsole compared to the 36mm in the Pro, offering a softer, more impact-absorbent ride for long runs.
Should runners over 80kg buy the Red Hare 9 Ultra?
It’s not recommended. Heavier runners may find the 44mm stack bottoms out too easily, increasing the risk of instability. Consider more stable models like the Nike Vomero 18.
