Detailed with side buckled straps, a rear engraved plaque and a cleated EVA sole, the collaboration gives the biker boot a distinctly current, fashion-forward silhouette. in collaboration with Willy Chavarria black slouched leather side buckled straps fleece lining back engraved willy Chavarria plaque cleated eva sole block heel
