    If you're looking for a lightweight running shoe you could use for racedays, speed workouts, anything like that, that has a litte bit of support built in, the Asics Gel DS Trainer is definitely going to be one of the better options out there.

  • 89 / 100 | Runner's World | Level 5 expert

    This revered trainer/racer gets back to its roots… That’s also helped bring this shoe back into the lightweight territory (two years ago, the DS Trainer weighed 9.2 ounces), making it a solid choice for intervals on the track and tempo runs on roads.

  • 85 / 100 | Solereview | Level 5 expert

    Half trainer, half racer, the supportive Asics DS-Trainer has held its own over the past two decades. Now updated with a Flytefoam midsole, and an ounce lighter than before.

    ASICS GEL-DS Trainer 22 has countless ways to make a girl cheerful.

  • Asics’ most advanced midsole technology in the FlyteFoam is clearly the biggest difference maker in this shoe. It brings more responsiveness without losing the stability and moderately-cushioned run that is a trademark of the DS Trainer series.
  • The outsole is another area where the Asics DS Trainer 22 gets a boost in performance. Most notable among the changes is the appearance of prominent star-like tread in the forefoot for a significant increase in grip despite the weather
  • A more subtle change in the outsole comes in the form of a slightly bigger and deeper Guidance Line that helps with the smoothness of the transition through the gait cycle and more flexibility.
  • Part of the reason why the latest model of the DS Trainer is very light is because of a more minimalist upper. There are lesser and thinner overlays that are well-positioned to give adequate midfoot hold, especially for those who over pronate a little.
  • Finally, better reflective details improve the safety precautions when running in low-visibility areas.

The Asics DS Trainer 22 generally runs true to size, but a tad narrower in the toe box. For those who have slightly wider feet, getting a size up should be a sensible option. The midfoot has sufficient security while an external heel counter locks down the rear portion. As it has a more glove-like fit, the entire shoe moves very well with the foot.

The outsole design is very typical of Asics, except for the well-appreciated enhanced forefoot treading. It is actually an improvement over the past model as the Asics DS Trainer 22 offers a better grip, including areas after a rain. The AHAR+ rubber is a staple in the underfoot construction as it prolongs the life of the outsole. This outsole material is also used in DS Trainer 24.

Running almost the full length of the outsole is a vertical cut that is also called the Guidance Line. The line makes the landing to toe-off movement efficient and smooth. A softer blown rubber, which is known in Asics lingo as DuraSponge, is utilized in the forefoot for more traction.

Asics packs the good stuff in the heart of the DS Trainer 22’s engine room—the midsole. As mentioned, the premium midsole technology in all of Asics’ arsenal is now featured here. The FlyteFoam is supposed to be 55% lighter than regular EVA with more cushioning, durability, and responsiveness. The resulting significant weight reduction is mainly due to the new midsole foam. Giving this shoe a lightweight stability is the Dynamic DuoMax or a touch of firm EVA under the arch that is encapsulated by a FluidRide foam to keep the ride smooth. The structural integrity of the shoe, especially around the midfoot is because of the TPU material hugging the lateral to the medial side of the midfoot. For better shock-absorption, the silicone-based Gel cushioning system is fitted in the heel.

The very simply simple upper is largely a combination of very breathable open mesh with minimal bonded overlays around the midfoot. With the seamless construction in the upper, runners are assured of a friction-free run. Providing some semblance of security in the heel is a prominent heel counter. A healthy interior is made possible by a ComforDry Sockliner that has anti-microbial and anti-odor properties.
