These black Balenciaga Tyrex sneakers feature an almond toe with a Tyrex logo, panels with layered rubber and mesh pieces, a slip-on design with laces at the front, pull tabs at the front and back and a logo at the heel counter. They have a moulded rubber sole. These space-age Balenciaga trainers belong on the Starship Enterprise. Even captains need some downtime (and leisurewear).
