The Chinese domestic running market has been a whirlwind lately, democratizing elite technology at prices that feel like a steal. Among these, the Dynafish (动鱼) Xiaonian (小年) caught my eye immediately. It wasn’t because of heavy marketing, but the promise of a nimble, plateless super trainer using premium, lightweight TPEE foam at an accessible price point.
As a runner with a smaller frame (5’5“, 125 lbs), finding a balance is tricky: I need something light enough to keep my turnover fast during speed sessions, but cushioned enough to save my knees without the rigidity of a full carbon plate. After logging over 500km across everything from track to rough concrete, I’ve got the full picture. Is this the holy grail of budget super trainers, or just old wine in a new bottle? Let’s dive in.
1. Technical Specifications
- Weight: 189g (US Men’s 8) – A staggering number, bordering on elite-level super shoe territory, ensuring a featherlight feel.
- Stack Height: 41mm (heel) / 34mm (forefoot) – An aggressive stack that exceeds standard thresholds, providing massive impact protection.
- Drop: 7mm – The sweet spot for midfoot and heel strikers alike, promoting a smooth transition.
- Midsole: TPEE (Thermoplastic Polyester Elastomer) – Next-gen foam offering high energy return and excellent compression set resistance.
- Plate: Plateless – Promotes natural foot mechanics and reduces the risk of muscle fatigue common with rigid plates.
- Outsole: Specialized high-traction synthetic rubber for durability.
- Upper: Ultralight mono-mesh for maximum breathability and weight savings.
- Street Price: Approx. $80 - $90 USD (converted).

2. On-Foot Experience
Right out of the box, the Xiaonian’s weight is shocking. It feels like holding a piece of foam—hitting 189g with a 41mm stack is an engineering feat. The initial step-in is comfortable, and the thin upper locks down securely without feeling cramped.
However, the stock insole is flimsy. After the first few runs, I swapped it for a 4mm ATPU insole from Dynafish. That small upgrade turned the Xiaonian into a beast: more responsive, better lockdown, and an even livelier underfoot feel.
3. Fit
For my foot shape (narrow-to-average, standard Asian sizing), the Xiaonian is perfectly true to size. The last is surprisingly roomy, making it very accommodating for wider feet. The toe box allows for natural splay, which is a lifesaver during long runs.
The security is excellent. The stock laces are long enough to perform a runner’s loop if you need extra heel lockdown, though honestly, I didn’t find it necessary. The minimal, thin tongue and integrated heel structure lock the foot in place remarkably well, even through sharp turns or sudden accelerations.

4. Cushion
Don’t let the “first generation” label fool you; the TPEE foam here is top-tier. You get a deep, cushioned sensation without the squishy, unstable feeling of inferior foams. Each landing is met with a quick, decisive energy return.
Because it’s plateless, my feet aren’t fighting a rigid carbon plate. The TPEE foam moves with my foot, allowing for a more natural gait cycle. At 125 lbs, I don’t need a carbon plate to get a snap, and the foam holds its shape beautifully even after 500km. No premature bottoming out here.
5. Stability
This is where I was most surprised. With a 41mm stack and no plate, I expected instability. Instead, it feels rock-solid—I’d rate it an 8.5/10. It’s significantly more stable than other plateless super trainers like the Evo SL. The wide base and flared heel create a stable platform that doesn’t twist or wobble, even when my legs start feeling heavy late in a run.
6. Ride & Distances
- Pace sub-4:00/km: The 189g weight is a huge advantage, but since there’s no carbon plate, you have to do more work to get the snap. Your calves will feel the extra effort compared to a plated racer.
- Pace 4:00 - 7:00/km (The Sweet Spot): This is where the shoe shines. The TPEE foam, combined with a gentle rocker, makes maintaining cadence effortless. Perfect for tempo runs or long efforts.
- Pace 8:00+/km (Recovery): It’s fine, but not ideal. The foam is designed to be responsive; when you run slowly, you aren’t compressing it enough to enjoy the energy return, making it feel a bit firm compared to dedicated max-cushion recovery shoes.
Distance: It’s an absolute winner for 5K to 21K. I wouldn’t push it to the full marathon (42K) distance, though—once you hit that late-race fatigue, you’ll miss the structural support of a plate.
7. Upper & Outsole
Breathability is top-tier. In the humid heat of Vietnam, my feet stayed cool and dry. The outsole rubber is holding up shockingly well; after 500km, the lugs are still sharp. I expect to easily pass the 1000km mark.
8. Daily Wear
As a shorter runner, the 41mm stack gives me a nice 4cm height boost. That said, it’s not a casual sneaker. The aggressive rocker and high-rebound foam make it feel strange to walk in or stand still for long periods. Keep this one for the road.
9. Who is this for?
- Lighter Runners (<65kg): You’ll get the most out of the foam without overloading the stack.
- Plateless Fans: Runners who want super-trainer performance but hate the harshness of a carbon plate.
- Pace Window: Best for those running at a 4:00 to 7:00 min/km pace.
- Avoid if: You want a jack-of-all-trades shoe for slow recovery runs or walking.
10. Value
At the $80-$90 price point, this is an incredible value. It delivers elite foam performance at a fraction of the cost of the big-name brands.
