Nike React Kiger 9 Trail Running Shoes

As the trail turns tough, go with the comfort and speed of the Kiger 9, there for every unexpected twist and tight turn. Equipped with full-length Nike React foam and a revamped breathable upper, this agile, quick trainer helps keep you zig-zagging in and out of trails with speed. It's lower to the ground and lighter than the previous iteration so you can shoot up that steep, rickety path with pace and security.

Engineered Mesh Upper

The upper of the Kiger 9 has been made using an engineered mesh upper. The mesh is highly durable, stronger and more flexible than standard mesh, making this perfect for hitting uneven and unforgiving trails. Due to being so light, this provides instant on-foot comfort, almost feeling like you don't have a shoe on. Perforations in the fabric increase airflow, creating a healthier environment for your feet to thrive in. When temperatures rise this well-ventilated upper ensures a constant cooling effect so you can power through any workout. A padded tongue helps to relieve pressure caused by foot swelling on long mileage runs; it sits comfortably against the skin to increase overall comfort. The collar around the ankle hugs the foot to ensure comfort whilst preventing dirt and debris from entering inside the shoe so you can continue with distraction-free strides. To the front of the shoes, Nike has covered the toes with a second "skin" to provide additional protection from rocks and debris. Completing the upper is a lacing system that locks down the midfoot to reduce in-shoe slippage so you can enjoy distraction-free strides.

React Foam Midsole

A full-length platform of React cushioning resides underfoot removing the forefoot Air unit from the prior model so that you can get closer to the ground without sacrificing comfort and speed. By doing so the Kiger 9 can deliver feathery durability plus smooth responsiveness. To produce this startlingly lightweight and springy midsole, crafted from synthetic rubber, Nike listened to the athlete. Their in-house sports research lab plugged footstrike data into a proprietary algorithm that determined how much cushioning was needed and where. They simulated testing on (about) one hundred possible shoe geometries quickly determining the handful they knew would work best for most runners then merged the science with an elegant design, intended to feel like a slipper on a mattress. The reactive nature of this clever midsole material means it absorbs impact and then expels it back out for a bounce-like effect. This energy-return technology reduces superfluous muscle power diminishing fatigue and enhancing performance, keeping you going for longer. Soft, generous and substantial, React will spare your joints as you strike down onto hard, unforgiving concrete and infuse every stride with the kind of zealous power that is often elusive in the running world.

Durable Rubber Outsole

Developed using a durable rubber, the outsole of the Kiger 9 ensures durable protection on the trails. The outsole has been constructed using abrasion-resistant materials to ensure long-lasting durability and grip. The durable rubber provides a strong grip on the most challenging terrain; it works to protect itself from damage and protect users from losing control and slipping. The abrasion-resistant rubber outsole protects you as you strike down and take off. The rock plate reduces the risk of damage to the foot from uneven terrain and rocks. Completing the outsole are multi-directional traction lugs made from high-abrasion rubber which can be found on the heel of the shoes. They help provide enhanced grip on descents and ascents so you can go further for longer with complete confidence. Grippy outsole lugs mean optimal grip and easy mud shedding, never killing your pace with weight, and they're strategically placed with a sharp, crisp shape to amplify grip in every direction, in every condition.
