The ANTA Zone 2 90 is a lightweight performance trainer that can handle everything from easy runs to progressive long runs. Its cushioning provides amazing protection that holds up impressively over longer distances, but the soft midsole and relatively narrow outsole might make it too unstable for some runners. Although our tests found it has less than the 90% energy return that ANTA claims in the shoe's name, it still has enough bounce to feel fun and lively. While the 90 in the shoe's name might be overselling, the "Zone 2" moniker seems limiting: this shoe can certainly handle comfortable cruising, but is just as capable at faster paces.

Our Verdict
The ANTA Zone 2 90 is a very good option for marathon racing, despite not being designed as such. Its light weight, good responsiveness, and impressive long-run cushioning mean it can go the distance without bottoming out. That said, its sub-par stability means it's not the best pick for those looking for more predictability underfoot.
Impressively nimble underfoot.
Very good long run cushioning stops it bottoming out.
Sub-par stability is problematic as the miles build.
The ANTA Zone 2 90 is a decent option for 5K and 10K racing. Its light weight and lively midsole make it capable of handling shorter races, but the soft forefoot and compliant rocker mean it lacks the sharp turnover and propulsion of more dedicated speed shoes.
Agile thanks to its light weight.
Lively midsole adds pep.
Soft forefoot lacks the snap of dedicated racers.
Compliant rocker limits turnover when pushing the pace.
The ANTA Zone 2 90 is a decent option for long runs. It offers excellent protection overall, with an energetic midsole that holds up impressively over long distances without turning mushy. However, its sub-par stability means it never feels as secure as dedicated long-distance shoes, particularly as the miles start adding up.
Ride is amazingly protective.
Midsole holds up magnificently without turning mushy.
Sub-par stability is problematic as the miles build.
The ANTA Zone 2 90 can handle daily training decently. Its midsole is deeply cushioned and amazingly protective, and it does a good job of adding excitement to daily miles. However, its stability is very disappointing for a daily trainer, meaning runners who need more support should look elsewhere.
Amazingly protective ride.
Enough pop underfoot to not feel dull.
Stability is middling for daily training.

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.
Test Results
Energy Return
The ANTA Zone 2 90 has excellent energy return overall. Its lively midsole delivers ample rebound, creating a bouncy ride that's excellent for runners who want some softness underfoot without sacrificing excitement.
Lively midsole is a joy to run in.
Effort is amply rewarded by the premium foam.
The energy return in the forefoot of the ANTA Zone 2 90 is excellent, and even comes in a bit better than the heel. The Nitro90 foam does an amazing job of giving back the work you put in and even outperforms shoes like the adidas Adizero Evo SL, making for an energetic toe-off that rewards runners at faster paces.
Stability
The ANTA Zone 2 90 has sub-par stability. Despite a reasonably wide forefoot platform, the narrow outsole arch and soft midsole mean the shoe struggles to feel planted.
Narrow outsole arch.
Soft forefoot provides little stability.
The soft heel of the ANTA Zone 2 90 is a definite drawback of the shoe. Regardless of your weight, pace, or strike pattern, it contributes to the shoe's poor stability and is best for runners seeking utmost plush comfort rather than first-class support.
Much like the heel, the forefoot contributes to the poor stability of the ride when striking or rolling through. Runners prioritizing softness over stability need not worry, but those who rely on a firm forefoot for snap and support will be better served elsewhere.
Similar to the adidas Adizero Evo SL, the ANTA Zone 2 90 features a partial plastic shank in the midfoot to help control the Nitro90 midsole.
Cushioning
The ANTA Zone 2 90 has excellent cushioning. Its deep, highly protective midsole absorbs plenty of impact and holds up impressively over longer distances without bottoming out. The ride is soft and deeply protective without turning mushy, making it easy to spend a lot of time in this shoe. However, runners who prefer a firmer, more traditional underfoot feel may find it a bit too compliant.
Deep cushioning provides excellent protection.
Forefoot cushioning holds up impressively as the miles build.
Comfortable at a wide range of paces.
Softness won't appeal to runners who prefer a firmer ride.
It offers superb cushioning and impact protection for lighter, slower runners and remains impressive across all weights and paces. Any runner looking for excellent protection in a versatile performance shoe will be well taken care of.
Though a bit less protective than the heel, the forefoot cushioning of the ANTA 2 90 is still great overall. It holds up impressively for most weights and paces, and the steady decline in protection is to be expected.
Bounciness
The ANTA Zone 2 90 has good bounciness. Its excellent overall energy return helps it feel lively underfoot, although it doesn't have enough foam to bounce back that forcefully.
Excellent energy return stops the ride feeling dull.
Snappiness
The ANTA Zone 2 90 is reasonably snappy, as the forefoot returns a lot of energy when bent, but it isn't quite firm enough for aggressive toe-offs.
The ANTA Zone 2 90 has great forefoot bending energy return. The shoe does an excellent job of returning the energy stored as the forefoot bends, helping preserve efficiency and contributing to its lively, bouncy ride. It doesn't create the aggressive snap of a plated racer, but it does help make the shoe eager and efficient when picking up the pace.
The forefoot flexes fairly easily, helping the shoe feel smooth across easy and steady runs. However, that flexibility also means it lacks the snappy toe-off and assistance found in stiffer, more race-focused shoes like the Nike Alphafly 3.
The ANTA Zone 2 90's rocker does a good job of guiding the foot through toe-off and keeping transitions smooth, but it isn't especially aggressive and doesn't create the forceful rolling sensation found in more dedicated speed shoes.
Roll
The ANTA Zone 2 90's rocker geometry smooths transitions and keeps the shoe moving forward; however, that rocker compresses quite easily under load, blunting propulsion and preventing the ride from fully capitalizing on its excellent rebound.
Rocker geometry is smooth and efficient in transition.
Flexible rocker blunts the shoe's natural bounce.
The rocker compresses quite easily under load, meaning some of the assistance from the geometry is lost once you're on the shoe. As a result, transitions remain smooth, but the ride never develops the forceful rolling sensation found in stiffer rockers like that of the ASICS SONICBLAST.
The ANTA Zone 2 90 has good heel rocker geometry. Its pronounced heel bevel helps smooth landings and makes transitions into midstance fluid. While it isn't among the most aggressive heel rockers we've tested, it still provides enough assistance to make the shoe feel natural over longer runs.
True To Size
The ANTA Zone 2 90 fits true to size overall. The length is spot on, and the forefoot has plenty of width for most foot shapes. However, the arch is quite narrow, and the toebox can be low for some, so runners with wider feet or taller toes may find the fit restrictive.
Length is true to size.
Narrow through the arch.
The ANTA Zone 2 90 is impressively lightweight, especially compared to rivals such as the adidas Adizero Evo SL. This, combined with its excellent energy return, makes it one of those rare shoes that you can almost forget is there.
The ANTA Zone 2 90 has impressive long-run cushioning, especially for a shoe in its class. The forefoot shows a steady, expected decline over the course of our simulated 50 km run, which translates to a shoe that is deeply protective well over marathon distance without bottoming out. Those looking for impressive protection for longer efforts will be very well served.

Differences Between Sizes And Variants
We bought and tested the ANTA Zone 2 90 in men's US size 9, as noted on the label of our pair. The pair we purchased is the White/Orange/Purple colorway, but you can also buy this shoe in other colors, depending on your region. The ANTA Zone 2 90 is only available in standard width. The design section applies only to the exact model we tested, but we expect other size and gender variants to perform similarly.
Popular Running Shoe Comparisons
The ANTA Zone 2 90 is part of the growing wave of lightweight, unplated, versatile trainers brought into vogue by the adidas Adizero Evo SL and taken further by the Dynafish Xiaonian. These trainers aim to provide high-end performance at much more accessible price points, combining ample cushioning with invigorating rides. Though the adidas and ANTA both use a plastic shank in the midfoot to help control the chaos, and the adidas is much more stable than the ANTA, they're not stable shoes by any stretch, with the Dynafish foregoing the shank and coming out the most stable overall. The ANTA is the peppiest underfoot of the trio, and though all are impressively protective, the Dynafish offers the deepest cushioning while still also coming in lighter than the other two shoes. This positions the ANTA somewhere in the middle, offering the liveliest ride of the trio, but its sub-par stability makes it the most chaotic of its rivals.
Within ANTA's performance running lineup, the Zone 2 90 is the brand's take on the unplated performance trainer. The ANTA C202 7 occupies the super trainer position, the ANTA C202 5 GT takes the more lively super shoe slot, and the ANTA C202 6 Pro is the lightest, most aggressive super shoe of all.

The Dynafish Xiaonian and ANTA Zone 2 90 belong to the same breed of lightweight, unplated performance trainers, though the Dynafish pushes the concept further. It's lighter, more cushioned, and more stable, making it the more complete shoe overall. The ANTA offers a bouncier ride, but its narrow midfoot and sub-par stability make it the less confidence-inspiring option over longer distances.
The ANTA Zone 2 90 and ANTA C202 7 are both lightweight performance shoes, but they fill very different roles in ANTA's lineup. The Zone 2 90 is the unplated all-rounder, pairing excellent energy return with deep cushioning and a soft, bouncy ride. The C202 7, meanwhile, is a carbon-plated super trainer designed for faster training and race-day efforts. Its stiffer platform and aggressive rocker make it more propulsive and efficient when picking up the pace.
The adidas Adizero Evo SL and ANTA Zone 2 90 are both lightweight, unplated trainers that blur the line between daily trainer and performance shoe. The ANTA offers more protection and better long-run comfort, with a softer, bouncier ride that makes it the more enjoyable cruiser. The adidas is firmer and a bit more stable, though it's still not the most stable shoe underfoot.
