JACKAL II Boa

The La Sportiva Jackal II BOA is a high-performance mountain running shoe for ultra-long distances. It features the scientifically tested and proven PerformFit™ Wrap powered by the BOA® Fit System for a fast, effortless precision fit. Dual Dial BOA® on the protective upper in combination with a double 3-layer microfiber closure flap ensure a perfect zonal adjustment across the foot for maximum heel hold.
