These Terra Kiger Trail Running Shoes by Nike have been developed with a Nike React foam midsole which is highly responsive and durable, while the Zoom Air unit in the forefoot provides even greater cushioning and energy return. The shoes have multidirectional lugs made from high-abrasion rubber for superior traction on ascents and descents, whereas the Dynamic Fit System through the midfoot helps hug and support your foot as your run through rocky trails and the rock plate at the heel helps shield your foot. The Terra Kiger shoes also benefit from having a mesh and synthetic upper for lightweight ventilation and the padded tongue helps relieve pressure when feet swell during long runs.
