Created for street runners with neutral pronation, the GEL-Nimbus 20 has a visible gel in the hindfoot positioned closer to the foot, able to simplify every step, making it softer and more comfortable, both for a half marathon and for an entire marathon. The Fluid-fit upper with gradient mesh offers a variety of levels to support the expansion and contraction of the skin of the foot.
