Germany's Solebox has partnered with PUMA to release two special iterations of the XS850 silhouette. The "Adventurer" pack consists of a light grey version of the sneaker, as well as a black and grey two-tone variation. The sneakers are constructed from suede, mesh, nubuck and neoprene, and feature contrasting splatter detailing at the heel. Solebox branding at the heel and insole complete the collaboration. The Solebox x PUMA XS850 "Adventurer" pack will be available in limited quantities online and at select retailers beginning in May.
