The Brooks Cascadia 9 Women's Trail Running Shoes are designed for long trail runs and keeping your feet comfortable mile after mile of tricky terrain, with adaptive support underfoot and plush cushioning. In an update to the Cascadia line, the 9th model features a lower heel and flat lacing. A lower-to-ground feel and a more secure lacing system allow you to run faster with fewer distractions. The dynamic BioMoGo DNA unit offers improved cushioning with a deluxe feel. The Caterpillar Crash Pad works to offer adaptive cushioning, ensuring you get a smooth and comfortable transition, step after step. The Pivot Post in the forefoot provides 4x4 like suspension, with adaptable support allowing your foot to make even contact with the ground and helps to prevent injury or falling. The Ballistic Rock Shield also serves to protect, keeping out stones, debris and stopping jagged rocks from penetrating the outsole and preventing any injuries.
