Updates to Gel DS Trainer 21

The 21st iteration of the Asics Gel DS Trainer is a daily training shoe that provides plush underfoot support and mild stability to those who need it. The mid-sole cushioning systems are efficient and the upper gives a secure and comfortable wrap. Wearing this shoe makes running easier and more agreeable to the runner.

Moving away from the plain and simple design of the DS Trainer 20, the Gel DS Trainer 21 offers a more appealing look that has a modern and sleek style. The value of the upper unit isn’t just about its looks, though. It uses a soft and breathable material that keeps the foot well-ventilated. The coverage is also snug and secure.

A bevy of mid-sole systems make up the plush and dependable platform of this running shoe. Comfort is received through a soft foam that also delivers rebound mechanics. A forefoot-and-heel impact protection unit makes sure that the foot stays safe from landing shock. The gait and running efficiency is guided by this high quality mid-sole.

The purpose of the outsole unit of the Asics Gel DS Trainer 21 is to bring durable protection against wear and abrasion, as well as delivering responsible traction over the roads. It’s also meant to be lightweight, so that it doesn’t drag the mid-sole down while still allowing flexibility.

Gel DS Trainer 21 size and fit

The Gel DS Trainer 21 features a standard running shoe length. It’s available in sizes that adhere to the regular measurements for men and women. The available width is medium, so it accommodates runners whose feet are medium-sized. This shoe’s semi-curved shape allows the natural shape of the foot to acclimate well to it.

Outsole

The Asics High Abrasion Resistant Rubber or AHAR® is a high quality rubber material that’s meant to deliver durable protection against the abrasive nature of the asphalt. Made from carbon rubber, it doles out its purpose well, and it also doesn’t peel off easily.

The DuraSponge® is a forefoot rubber compound that adds a bit more cushioning to the runner, particularly during toe-off. Its responsive and flexible, so it allows the foot to move as freely as it can as it delivers traction and protection.

The DuoSole® design doesn’t make the external layer heavy or thick. It allows the rubber materials to do their job well, though it reduces weight. Traction, flexibility and durability are all preserved.

Midsole

The Solyte® is a full-length foam that delivers responsive cushioning to the runner. It has a springy nature, so it makes each step more efficient and energized. It’s made from high quality materials, so it doesn’t break down easily.

The Gel® Cushioning System is a gel unit that’s based from silicon. It’s placed separately in the heel and forefoot sections. It handles the impact shock when landing the foot on the ground, so the runner stays confident and protected throughout every running activity.

The Lightweight Dynamic DuoMax Technology is a dual-density mid-sole foam that stabilizes the mid-foot of the wearer. It responsibly supports the arch and guides it to a more neutral stance, so that the runner stays efficient and free from discomfort or injury when running.

The Guidance Line® is a visible vertical flex groove in the upper that leads the foot to a more efficient running gait, while an Impact Guidance System® is a mid-sole construction that balances the transition from the heel to the toe.

The Propulsion Trusstic System is a unit that’s made from thermal plastic. Used to connect the medial mid-foot and the lateral heel section, its purpose is to propel the runner forward on each step.

Upper

Open Mesh is a soft and breathable material that’s used in the Asics Gel DS Trainer 21. It constantly encourages air to enter the shoe and keep the foot cool and dry throughout every activity. It’s also pliable, so it follows the movements of the foot well.

The Seamless Upper Construction limits the use of stitching and virtually removes seams out of the picture. Instead, the overlay system is fused onto the upper, reducing the overall weight of the shoe and allows unrestricted movement.

The Heel Clutching System™ is an exoskeletal heel part that holds the rear of the foot in place. It prevents any slippage or accidental shoe-removals, essentially making the fit surer and more secure.
The ComforDry™ gives the runner additional cushioning. Placed just above the mid-sole unit, it also keeps the interior environment clean and healthy because of its anti-microbial and anti-moisture properties.
