Some people prefer to save the weight, others excel with more mobility in the ankle. Whatever your tactic, the Mantra 2.0 GTX invites you to take things further. Sure, it's a low-cut, but the Vibram Nuasi sole and molded polyurethane midsole reward you with the same stability and grip as a backpacking boot. And the Mantra 2.0 GTX relies on GORE-TEX for its climate control. The mobility of a runner, but the burliness of a boot make it your mantra.
