Trail running takes a lot of energy and gets you breathing hard. The Mens Zenon Track Low Shoe has been designed as an extra lightweight running shoe, because the less weight your feet have to carry, the more energy you can direct towards achieving your goal. Even putting them on is easy, with one pull of the rapid lacing system. From the very first step you take in the Zenon you'll notice just how light and airy they feel. Jack wolfskin have constructed the upper entirely of mesh fabric; making the shoe very flexible and providing a super comfortable fit. The sole is designed to promote stability by supporting your foot and cushioning your every step, so you and your feet stay fitter for longer.
