The wool tweed upper of their Hack style is what really sets it apart from all others. The nubby texture is infused with colored flecks, just another cool detail that makes them pretty special this season. Sitting on an articulated outsole gives it a real dynamic appearance especially from the side and you're gonna enjoy how great they feel once you're out and about in them. Contrasting stitch detail and padded insole for comfort. Material: Wool, Man Made.
