The Alverstone II GTX is designed to provide a lightweight, yet sturdy fit for challenging terrain. Thanks to its innovative, LFX (Lateral Flex) construction, it’s the ideal choice for long summit trips and multi-day alpine treks. The modern, shock-absorbing Vibram® sole construction with lower stack height provides additional stability in rugged terrain. And the GORE-TEX lining keeps your feet dry in wet and snowy conditions.
