I would probably be reluctant to spend much time off trail in the Koa TR (but would certainly consider the Koa ST with 8mm lugs), but aside from steep, loose off trail and perhaps snowy, icy winter conditions, the Koa TR is a fine choice, especially if you run from your doorstep.
A new addition to the Saucony trail line-up, the Koa TR is perfect for city runners whose trail running mostly consists of off-roading in parks with the odd trip out to the countryside. The Koa TR is comfortable enough to run on roads, while the 4mm lugs give just enough grip to cope with a range of trails – although you obviously wouldn’t want to try speeding through a bog in them.
This shoe will get you through the roughest terrain. On a drier course, it will be great. For a race with a lot of mud, the drainage is a consideration when buying. Overall, this could be a decent OCR shoe for the right race.
The shoes were pretty responsive and transitioned well from pavement to boardwalk to a packed trail and finally off the trail. My heel locked in nicely and my toes had ample room to move where needed. The shoe is wide enough for my foot and my feet had a comfortable ride on the trail.
Updates to Saucony Koa TR
- The Saucony KOA TR is a versatile shoe that is built to function on- and off-road; it performs well in a wide variety of conditions, including technical trails. Both the outsole tread and midsole unit allow the shoe to be responsive and efficient in transitioning from the pavement to the trail.
- The innovative EVERUN midsole allows the shoe to be responsive while still providing ample cushioning throughout the run.
- It also features the FlexFilm technology, which provides lightweight support, strength, and comfort while retaining foot security for a stable motion.
- The 4-mm heel-to-toe drop delivers a more natural ride, letting the foot exert more effort by not allowing it to be complacent with the shoe’s cushioning and stability features. This, combined with the small weight and midfoot strike, results in an excellent speed.
Saucony Koa TR size and fit
The KOA TR is a lightweight trail running shoe that caters to the foot with neutral pronation. It provides the foot with a secure fit, and the shoe technologies allow for a locked-down feel. The oblique toe box results in a wider toe room, so while the length runs true to size, runners with a high-volume foot will also appreciate this shoe. Width profiles are available in D – Medium for men and B – Medium for women.
Using the PWR TRAC outsole, the KOA TR is engineered to adapt to various terrain types with its excellent traction and durability. It offers enough grip to keep the foot secure, even on the most uneven surfaces.
The outsole also includes a more versatile lower lug pattern that provides extra grip, thus making it more effective on both hard surfaces and uneven terrain. Although quite minimal, the 3.5 mm lugs make running easier because they allow the sole to roll smoothly, keeping the runner sure-footed no matter the terrain. They are made from a sticky rubber compound that is capable of handling sloppy and muddy conditions.
Featuring Saucony’s unique EVERUN technology, the EVA midsole provides the right blend of firmness, cushioning, and responsiveness. EVERUN delivers significant key benefits: it absorbs impact shock three times better than standard EVAs, returns 83% of the energy absorbed, and it lowers peak pressures as the underfoot conforms to the shape of the foot and distributes force across a larger surface area.
Made from tiny pellets of polyurethane that are heat-expanded and molded into a single cushioning unit, EVERUN has a definite firmness that allows for a resilient ride.
Despite the relatively low stack height, the midsole of the KOA TR provides the right amount of protection and support. It is bouncier and allows for smoother landings and stronger takeoffs.
The upper of the KOA TR is made from woven mesh that is flexible, tough, and breathable that works double-duty as a protection from debris and rocks and as an evacuation system that sheds water well, enabling the foot to stay cool, dry, and at ease. Its secure finish delivers durable foot-wrapping and adequate ventilation.
Using the FlexFilm technology, there is an exoskeletal support frame for an enhanced strength and comfort. It is fused with the upper mesh material, reducing the amount of stitching and thus creating a soft and almost seamless surface against the runner’s foot.
FlexFilm overlays are also present to secure the foot in place and minimize any unwanted movement for a stable run. It runs in a crisscross design across the midfoot and the through the forefoot so the foot is comfortably locked into place.
The toe box is oblique-shaped for additional toe room, allowing maximum toe splay and therefore improving balance, especially when pushing the pace on moderate to technical trails.
Heel support is present through the heel collar that is made plush for added comfort, and the heel counter that is made sturdy and secure. A reinforced heel piece is also positioned in the upper for added protection and locked down fit.
There is also a plush, non-gusseted tongue which rides independently beneath the booty upper throughout the lace area. This design delivers a snug yet comfortable protection for the ankle.
