Dynafish is one of the more mysterious players coming out of the Chinese running market. They aren’t mysterious because the product is bad—quite the contrary—but because, despite all the social media hype, you almost never see them in the wild. Not at run clubs, not on city streets, and not at long-run meetups. But that “underground” status is exactly what makes the Xiaonian—affectionately known as the Small Fish—one of the most intriguing shoes to hit the market recently.
Dynafish markets the Xiaonian as a “super trainer,” a category with increasingly blurred lines: it’s not quite a pure daily trainer, yet not a full-blown carbon-plated racer. It sits right in the middle—high stack, lightweight, snappy, and cushioned enough for long hauls while still begging you to pick up the pace when the mood strikes.
Specs: Tall, Light, and Plate-Free
The Dynafish Xiaonian features a 41 mm heel stack and a 7 mm drop, putting the forefoot at 34 mm. This is a massive stack height, technically race-illegal, fitting the profile of a modern, max-cushioned super trainer.
The first standout detail is that Dynafish skipped PEBA for this model, opting instead for TPEE-based foam. This material tends to be more durable and provides a more controlled, stable ride while retaining excellent energy return. You’ll even see DMN branded on the midsole—the name of the factory behind the foam—a rare instance of co-branding that shows Dynafish is taking material science seriously.
Weight: 225 grams for a size 45, which is remarkably light for the super trainer category. Compared to its peers, the Xiaonian feels significantly more nimble and agile underfoot.
The sizing is true-to-size based on Chinese standards, but if you’re coming from major Western brands, be sure to double-check your conversion.
Upper: Minimalist, Performance-Focused
The Xiaonian upper uses a TPU-pressed mesh. Right out of the box, it feels comfortable with zero break-in time. The material isn’t stretchy, but there’s enough volume that it never feels restrictive.
The tongue is made from a wetsuit-style fabric with dual gussets to keep it locked in place. The collar has just enough padding—no heel rub, and it doesn’t soak up sweat. However, the heel counter is quite soft and lacks any real internal structure. It’s a double-edged sword: you get reduced weight and increased comfort, but you might miss that sense of security during sharp turns.
The toe box is quite roomy, catering well to wider Asian-foot shapes. However, the midfoot lockdown is aggressive, creating a very snug wrap around the arch. This helps with responsiveness, but if you have flat feet or a low arch, you might feel some pressure in that area.
Midsole: The Heart of the Xiaonian
If I had to describe the midsole of the Dynafish Xiaonian in one word, it’s “chewy.”
The TPEE foam feels plush on impact but doesn’t bottom out; it compresses and then delivers a distinct, snappy rebound. It’s not the “mushy” feel of older EVA, nor is it as harsh as some race-tuned PEBA foams. It lands in that sweet spot: fun underfoot, yet well-controlled.
Dynafish also promotes a “heat-conducting column” in the heel, reminiscent of Nike Shox. In reality, if you pull out the insole, you can see this structure acts as an additional support zone for the heel—which is particularly beneficial for heavier runners or heel strikers.
The durability is impressive. After long runs of up to 35 km, the midsole retains its bounce without “dying out”—a crucial trait for any super trainer.
Real-World Ride: The Faster, The Better
At a pace of around 5:00/km (roughly 8:00/mile), the Xiaonian really finds its stride. This is the shoe’s “sweet spot”: there’s enough force to get the foam to rebound, and it feels smooth transitioning from heel to toe.
When hitting hills, the midfoot landing feels very natural, utilizing that thick block of foam under the arch. It’s clear the Xiaonian is designed for midfoot strikers, though heel strikers will still find it perfectly capable.
At recovery paces, it’s fine, but not exceptional. It lacks the “cruise control” smoothness of a dedicated max-cushion cruiser. However, when you crank the pace up to threshold, tempo, or even fast strides, the shoe comes alive.
One reviewer put it perfectly:
“This isn’t a shoe for a casual jogger—it’s a shoe for someone who actually pushes the pace.”
Outsole: Sticky and Durable
The outsole uses CPU rubber. After about 45 km, there is almost no visible wear, even on the smaller lugs. This is a huge win for high-mileage runners who rack up the distance.
It grips well on dry and light damp roads. It’s not a specialized trail or monsoon shoe, but it’s more than enough for everyday road training.
The Downsides
No shoe is perfect, and the Xiaonian has a few quirks:
- Cheap Insole: It flattens out quickly and feels low-quality compared to the rest of the midsole.
- Slippery Interior: The combination of the tongue and the stock insole can lead to foot sliding if you don’t lock your laces properly.
- Soft Heel Counter: Not the most stable for technical corners or track sessions.
- Narrow Midfoot: Runners with wide feet should exercise caution.
A practical tip: Don’t take the Xiaonian to the track or use it for frequent, sharp cornering.
Where does the Xiaonian fit in the “Running Ecosystem”?
If we map it on a Speed vs. Distance axis:
- Compared to daily trainers: Faster and lighter
- Compared to max-cushion cruisers: Less plush, but more agile
- Compared to tempo shoes: More cushioned, better for long efforts
- Compared to carbon racers: Less “snap,” but more durable and accessible
The Xiaonian doesn’t try to do everything. It is unapologetically a speed-oriented super trainer, best suited for:
- Pace-controlled long runs
- Marathon training blocks
- Steady, progression, and long tempo workouts
The Verdict: Value-to-Performance King
You can often find the Xiaonian for under $100 USD (or equivalent) through international shipping services. At that price point, the value is impossible to beat.
It isn’t a “hype beast,” but it is one of those shoes where:
“The more you run in them, the more you appreciate them.”
Final Thoughts
The Dynafish Xiaonian is a very good to great shoe, especially for runners who:
- Want a lightweight super trainer
- Crave a responsive, energetic ride
- Train high volume with specific pace goals
It’s not for everyone, but for the right runner, the “Small Fish” is swimming very fast in a sea of massive competitors.
