The La Sportiva Jackal II Boa features an innovative outer and midsole set made of dual-density EVA foam, offering additional cushioning and increased stability. 

The Infinitoo™ technology, consisting of two internal polyurethane cushions, offers excellent shock absorption and high energy return. As a result, running in these shoes is a pure pleasure, regardless of the distance.

The double flap made of microfiber in three layers ensures airtightness and flexibility. This, combined with the SpiyralFit tongue construction and the collar made of multilayer Ariaprene foam, provides protection against impacts and prevents the ingress of contaminants while ensuring high breathability.

The double BOA® Fit system guarantees maximum heel hold and optimal volume adjustment in the forefoot area of the shoe. This ensures a perfect fit around the foot, promising stability and comfort while running.
