A lightweight version of the popular Mountain Trainer Mid GTX, the Lite is over four oz lighter than its predecessor. The signature 3F system connects the instep area with the sole and heel for flexibility, correct fit and support. Climbing lacing provides a more wrapping fit at the forefoot. And 3D eyelets allow customized three-zone lace tensioning - you can also fine-tune the toe-area for greater precision and support in technical terrain. Gore Tex Performance Comfort Lining keeps feet dry in wet conditions.
