The Jackal II Boa trail running shoe from La Sportiva is a performance-oriented mountain running shoe for ultra long distances and experienced trail running athletes. It comes with a double BOA twist closure for quick and perfect volume adjustment, even while running. 

The protective upper and Ariaprene collar come with a precise, snug fit that provides stability even on the most technical sections of an ultra marathon. The double closure flap made of 3-layer microfiber contributes to this, as well as the Double Boa Fit System with maximum heel hold.

The midsole was developed exclusively by La Sportiva to provide perfect shock absorption and guarantee maximum energy return while running. The soft polyurethane that makes up the structure of the Infinitoo midsole ensures long-term unchanged high damping performance. The sole is a dual FriXion Red compound with lateral IBS lugs.
