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 zigzagging 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

Made from an engineered mesh, the uppers of the Terra Kiger 9 are highly durable, stronger and more flexible than your standard mesh, making the shoes great for hitting the constantly changing terrains of the trails. Due to being so light, this provides instant on-foot comfort, almost feeling like you don't have a shoe on. Perforations increase airflow, to create a better, healthier environment for your feet to thrive in, meaning this well-ventilated upper ensures a constant cooling effect so you can power through any workout with ease. A padded tongue helps to relieve pressure caused by foot swelling on long mileage runs and sits comfortably against the skin to increase overall comfort. A collar around the ankle hugs the foot to ensure added comfort and also prevents dirt and debris from entering 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 added 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 voice of 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 to quickly determine the handful they knew would work best for most runners and 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 the use of 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 Nike Kiger 9 Trail Running Shoes 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 during 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 which are made from high-abrasion rubber and 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.
