The Jackal II BOA is a performance-oriented mountain running shoe, designed for ultra-long distances.

Featuring the BOA® Fit System, the dual BOA® wheels allow for quick adjustments to the heel and forefoot, creating a precise and snug fit so you can dial in and hit the trails with confidence. The scientifically tested and proven PerformFit Wrap works with the BOA® Fit System, which makes the fit micro-adjustable, contributing to increased stability and reducing landing impact. The adjustability of the shoe is truly customisable, thanks to the two BOA® casters on the sides that allows the shoe to be tightened or widened based on the areas of the foot and the runner’s need.

For novice and elite ultrarunners alike, the Jackal II is equipped with a new lightweight upper made from eco-friendly materials, as well as an innovative midsole that combines Infinitoo Polyurethane inserts with compressed EVA to create a soft yet responsive ride. The Spiyralift tongue and collar cradle the ankle for increased proprioception and protection.
