The Dynafish Xiaonian is a lightweight, high-stack, unplated performance trainer from emerging Chinese brand Dynafish. Built around a full-length TPEE midsole and a pronounced rocker, it aims to deliver a smooth, protective ride across pretty much any pace or run length. In a market crowded with unplated, do-it-all trainers like the adidas Adizero Evo SL and Saucony Endorphin Azura, it's hard for a lesser-known brand to stand out. Still, Dynafish manages to do exactly that with an impressive mix of premium foam, low weight, and a responsive ride that comes from its rockered geometry and bouncy midsole. At slower paces, it feels stable and protective enough for easy miles. The magic really comes from the midsole when you pick up the pace, where it feels very propulsive and well-suited to faster workouts or even some racing.
Our Verdict
The Dynafish Xiaonian performs very well for marathon racing, although it's designed primarily as a training shoe. Its very light build, highly cushioned midsole, and responsive forefoot make it efficient and forgiving over long efforts, while its rockered geometry helps it roll smoothly through toe-off. However, its unplated design gives it less bending stiffness than a carbon-plated super shoe, so the rocker flattens out a bit more under load instead of delivering the same snap.
Very light for a trainer.
Strong forefoot energy return.
Rockered geometry helps smooth toe-off.
No plate means the shoe isn't very stiff.
The Dynafish Xiaonian isn't truly designed for 5K and 10K racing. Its low weight and energetic midsole help it feel quick enough for faster efforts, and it has enough rebound to handle intervals, tempo work, and shorter races. That said, its forefoot isn't the snappiest as the absence of a plate limits the powerful toe-off sensation you get from dedicated short-distance racing shoes.

No plate means the shoe isn't very stiff.
The Dynafish Xiaonian is very responsive for an unplated shoe. Its midsole returns energy well under both the heel and forefoot, and the pronounced rocker helps create a propulsive, rolling transition when you pick up the pace. It doesn't feel as rigid as a plated super trainer, since the forefoot doesn't have much bending stiffness, but that also makes it feel smoother and more adaptable across different paces.

The Dynafish Xiaonian has outstanding cushioning. It delivers a very high level of impact protection under both the heel and forefoot, making it well-suited for high-mileage running and runners who want a lot of foam underfoot without a sluggish feel. The midsole has enough absorption capabilities to be suitable for long runs, though its cushioning becomes noticeably less protective after very long efforts than it feels at the start of a run.
Excellent impact protection under heel and forefoot.
The Dynafish Xiaonian has decent lateral stability, especially considering its tall stack and soft midsole. Its wide outsole platform, especially at the arch, helps it feel controlled through regular road running and longer efforts. Still, the softer foam underfoot keeps it from feeling especially super planted during sharper turns or uneven landings.
Wide outsole platform adds stability.
Soft heel can feel less planted.
The Dynafish Xiaonian fits true to size. Its length, width, arch volume, and forefoot height all closely match our reference fit, so most runners should find it easy to get a natural fit in their usual size.
Fits true to size in length and volume.
Performance Usages
Differences Between Sizes And Variants
We tested the Dynafish Xiaonian in men's U.S. size 9, as indicated on the label of our unit. The specific colorway shown here is "Black 目中无人", which vaguely translates to "Be stuck-up". This model is available in additional colors as well. Availability is still variable depending on the region; in North America, it's possible to find the shoe through some online retailers, such as shopnings. Most of our review results are valid for all variants, though the design section applies only to the model we tested. We expect other size and gender variants to perform similarly.
Popular Running Shoe Comparisons
The Dynafish Xiaonian is a lightweight, high-stack performance trainer that pushes the current wave of unplated do-it-all trainers a step further. It follows the same general formula as popular shoes like the adidas Adizero Evo SL while addressing many of that shoe's biggest flaws: it's less chaotic underfoot and feels even more propulsive thanks to its very bouncy foam and more pronounced rocker. Similar uptempo trainers like the Saucony Endorphin Azura and Kiprun Kipstorm Tempo also aim to balance protection for daily mileage with enough responsiveness for faster workouts, but they don't match the Xiaonian's low weight, which gives the Dynafish a more nimble feel that's especially noticeable when picking up the pace.
Within Dynafish's young lineup, the Xiaonian is only the second running shoe after the carbon-plated Silurus 1.0, making it especially impressive that the execution already feels this refined.

The adidas Adizero Evo SL and Dynafish Xiaonian are two uptempo trainers built around energetic midsoles, but the Dynafish pushes the concept further. It is lighter, higher stacked, more protective, and more responsive overall, feeling almost like an elevated version of the Evo SL. The adidas uses a plastic shank to slightly firm up the midsole, while the Dynafish is completely unplated and relies more on the performance of its foam and geometry to create speed and propulsion.
The Kiprun Kipstorm Tempo and Dynafish Xiaonian are both versatile trainers that can handle daily mileage but feel most at home during uptempo running. The Dynafish is lighter and uses a full-length TPEE midsole that feels much bouncier and more energetic overall, while still providing plenty of protection for longer runs. The Kiprun is higher stacked, with its FastTech+ A-TPU foam sitting above a firmer EVA-based carrier layer, creating a more controlled ride that feels slightly less propulsive. It also has quite an aggressive geometry that feels less forgiving.
The Saucony Endorphin Azura and Dynafish Xiaonian are two unplated uptempo trainers, but they approach this role differently. The Dynafish is much lighter, more efficient, and more cushioned, giving it a more refined feel overall. The Saucony has a bit more bending stiffness through the platform that creates response, but the Dynafish uses a more aggressive rocker that feels more propulsive in the traditional sense, actively helping roll you forward through each stride.
We buy and test running shoes with a very data-oriented approach. While we're just getting started, our methodology already has dozens of tests to help you make the right purchasing decision for your needs. Not only do we use high-end equipment to gather objective data, but we also order multiple sizes of the same shoes so team members can log in miles. This real-world testing is conducted at various paces and conditions, across different types of workouts, to cover all the bases. This allows us to verify our results and ensure they align with what you might feel with a specific pair.
