The Salomon Wings Sky GORE-TEX 2 Waterproof Trail Running Shoes feature a three pronged support system which will offer you a superb running experience, allowing you to tackle the terrain with ease. The AC Skeleton works to adapt the shoe to changing terrain, holding the foot securely in place through the transition from heel to forefoot, giving you a stable step, every single time. The AC Muscle 2 cushioning midsole, ensures that through this cycle, you maintain maximum comfort, staying safe in the knowledge that you have a responsive and durable unit under you feet protecting you. The AC Tendon offers you a boost through the running cycle, absorbing the impact energy when heel-striking and helping transfer it out of the shoe when taking off, giving you a spring in your step. These technologies ensure you feel like you have a stable platform under your feet, no matter what terrain you are trekking over. New features include a Debris Gaiter to keep out stones and dirt, keeping you comfortable as you run. The Non-Marking Contragrip Outsole has also been improved to be more grippy on a range of surfaces and the Rubber Toe Cap has been extended to offer greater protection for the forefoot. The Lacing System has also been improved with reinforced studs holding the laces in place and easy on/off of the shoe.
