There is a rhythm to putting in your hardest effort. It lies in the crescendo of your heart rate, the quickening cycle of inhales and exhales, and the drumming of your feet against the ground. It follows the swing of your arms and the strides of your legs, a movement melody that accompanies the steadfast tenacity found in testing the boundaries of your exertion. In these endeavors, there is reassurance in running gear that harmonizes with your persistence, found in the silky soft feel of the Twilight and the stability provided by the Allston collections, now available in new colorways and updated to meet you at your highest intensity.
