he Xerocole Expedition is built for the extremes of off-trail adventure. The full-grain leather upper provides extreme protection and durability. The 7.25” boot height provides ankle support on uneven terrains while the high-traction, recycled rubber sole and a shock-absorbing cork footbed deliver the grip and comfort needed to navigate the world’s harshest terrain. The Xerocole Expedition is part of the world’s first Biocircular hiking collection. All Day Comfort: Erem’s shock-absorbing insole firmly cradles the foot with a contoured and molded cork footbed that promotes long-term foot health. Handmade in Portugal from rescued cork crumb, the insole is topped with just the right amount of natural latex foam for plush, all-day comfort.
