The Transcend 7… maximum cushioning with industry-leading support. A reconfigured midsole and outsole ratio allow an increase in DNA LOFT for even more extreme softness underfoot without losing responsiveness or durability. Brooks has shifted their focus beyond the feet to the most injury-prone part of a runner's body: the knees. GuideRails keep you moving comfortably by keeping excess movement in check. The plush feel of an internal stretch bootie surrounds your foot and moves and expands with your stride. The engineered mesh upper and 3D Fit Print technology only enhance the fit.
