The Jackal II Boa is the ultimate high-performance mountain running shoe designed to take on distances ranging from sky/ mountain running up to long ultra distances across rough, technical terrain.
The Jackal II Boa shares the same sole package as the Jackal II which is equipped with Infinitoo cushion technology for less energy expenditure but long term support and comfort. The protective, eco-friendly upper with Boa lacing system allows an incrediblly precise and secure fit - it ensures stability even on the most technical sections of trail. The Boa also allows quick adjustment on the move.
The Boa version of the Jackal II, although the same length wise, is slightly narrower and lower in volume throughout the forefoot. This makes them the perfect choice for racier or more technical terrain, effectively utilising this fit and the Boa system to ensure the perfect, dialled in fit for ultra-precise movement.
If you are regular Jackal I wearer, we advise sizing up half a size for the Jackal II Boa and Jackal II.
