Underpronation is what happens when a runner’s foot hits the ground at an outward angle but does not roll inward to absorb the shock of the landing. This leads to an increased amount of shock to the lower leg, which is why runners who underpronate benefit from a well-cushioned shoe. Runners who underpronate notice a marked wear pattern on the outer edges of their shoes, in the heel area as well as toward the forefoot. Runners who underpronate also tend to have high arches, making the ASICS GEL-Nimbus 21 the perfect complement to their anatomy thanks to its cushion and shock absorption. Learn More

Have a Neutral Arch

In an ideal gait, the foot lands slightly on the outer edge of the heel and then rolls inward to absorb the shock of the strike. For neutral runners, this ideal gait comes naturally, and most running shoes on the market today are designed to be suitable for neutral runners. Runners with a neutral gait notice a wear pattern on their shoes that is evenly distributed across the heel, if not slightly more worn on the outer edge, and the area beneath the ball of the foot will display even, centralized wear. Neutral runners tend to have normal arches and will find the ASICS GEL-Nimbus 21 to be a comfortable, energetic running shoe. Learn More
