DESCRIPTION EXOSTRIKE features a mix of leathers and colours especially developed for our Brigade collection. This award-winning shoe combines advanced functionality of a men’s fast hiking boot with the sharp, futuristic aesthetic of a street-smart sneaker. With its ribbed midsole, distinctive external heel stiffener and a rugged rubber outsole with exceptional grip and durability, this low top shoe is a superb example of the fusion between outdoor and lifestyle. LEATHER These two leathers create the softest but most technical combination. The abstract camo leather is nappa leather with a unique digitalized camo print, especially developed for W-21. This leather is highly technical as it is ultra light, ultra strong, ultra thin, and ultra soft. Celeste XA is the signature nubuck leather for W-21 and has a soft and soapy touch.
