SummaryThe Saucony Koa St is a trail shoe that features 8mm lugs and can handle a variety of terrains. These shoes can be used on dry trails, but excel on muddy, loose, and even steep terrain. The oblique toebox allows for a natural toe splay, although women did find the toe box allowed for more room than the men’s version.
The midsole of the Koa St features a 3mm EVERUN topsole for comfort and responsiveness. It distributes shock evenly while conforming to the shape of your feet.
A synthetic upper keeps moisture away, although this feature makes the shoe less flexible than the Koa TR. Furthermore, while the upper is great at keeping moisture away, it is not very breathable so you may find your feet getting hot in warm weather. Flex Film overlays on the upper help the shoe wrap firmly around your feet for a more secure feel. In addition, the reinforced heel aids in keeping your feet in place while protecting your Achilles.
The outsole is where the shoe really shines. It features PWR TRAC outsole is tacky, durable, and keeps traction on all types of terrain. The outsole also has 8mm lugs that face in different directions to help with traction.
