La Sportiva Jackal II BOA

La Sportiva Jackal II BOA review: what runners say

Fit

Narrow, snug fit built on the Tempo last; the BOA version runs lower volume than the lace-up Jackal II. The shoe skews narrow — sizing up half a size is recommended.

Feel

Firm, protective ride with Infinittoo PU inserts that add energy return without noticeably softening the platform. Not a cushioned shoe; those seeking plushness are outside the target.

Durability

Midsole and upper construction are aimed at 500–700 km; one source ventures 700+ km, BITR estimates 500–600 km. Frixion XF 2.0 outsole rated Grade A for grip and longevity.

Best for

Technical mountain terrain, steep ascents and descents on dry rock. Designed for mountain ultra distances; not suited as a daily trainer on mixed routes or deep soft ground.

Weak points

Narrow fit penalizes runners with wide feet or those on their feet for more than an hour: forefoot discomfort reported across multiple sources. Some runners report difficulty locking down the heel with the BOA system despite good lockdown at the forefoot and midfoot.
