  • The Saucony Koa ST is a trail running shoe that is designed for runners who have neutral foot motion. The shoe uses the PWR TRAC outsole. Its hexagonal-shaped pattern quickly adapts to different kinds of terrains.
  • With its 8-mm lugs, the right amount of traction is provided for uneven surfaces.
  • Featured in the midsole is the EVERUN technology which aims to deliver the right blend of responsiveness, firmness, and comfort that runners needed during their activities.

The Saucony Koa ST runs true to size. It provides a snugger and more comfortable fit to medium-footed runners. The shoe is available in standard medium B and D widths for the women’s and men’s respectively.

The PWR TRAC outsole is integrated into the Saucony KOA ST. When compared to the traditional rubber, the PWR TRAC offers more traction. This material is a tacky rubber compound that is essential in adapting to various types of terrains. It provides added durability as well.

To increase the level of traction, the KOA ST utilizes the 8-mm lugs. It provides enough grip on slick, muddy and soft trails as well as other uneven surfaces.

A responsive cushioning compound called the 3-mm EVERUN Topsole is utilized in the shoe. This technology aims to aid in the distribution of forces over large areas. As a result, it creates a high energy return in every stride. Because of the right combination of cushioning, responsiveness and firmness, better shock absorption is encouraged. It also lessens underfoot pressure as the material conforms to the natural shape of the foot.

The synthetic upper is integrated into the Saucony Koa ST. It ensures to resist mud and water from entering the shoe while maintaining its lockdown fit.

Welded to the upper area are the Flex Film Overlays. These materials are made up of a thin film that provides a more secure fit.

To prevent debris and other hazardous materials from entering the shoe, the gusseted tongue is utilized.

Featured in the Saucony Koa ST is the Toggle lacing system. This adjustable and flexible material is essential in creating a more precise fit.

Utilized in the shoe is the Lace garage. Its primary function is to tuck the laces out of the way while the wearer is running.

The Reinforced heel piece is used in the Saucony Koa ST. It protects the Achilles area while maintaining a locked-down fit.

Saucony added the Perforated Sockliner. This component of the shoe enhances breathability. It also aims to provide additional underfoot cushioning.
