The Jackal II BOA is a performance-oriented Mountain Running® shoe designed to take on any distance but built with Ultra-Long distance adventures in mind. It shares the same sole package as the Jackal II which is equipped with Infinitoo® cushion technology for less energy expenditure. The protective upper with a precise and secure fit ensures stability even on the most technical sections of trail while the double BOA® Fit System makes heel/forefoot volume adjustments a breeze while on the move.
