Hopeless space invader Zim is sent by his planet's leaders on a mission to infiltrate earth. He is constantly plotting Earth's downfall with the aid of his malfunctioning and dimwitted robot, GIR, but despite his access to Irken technology, his plots are never successful. These Invader Zim socks feature GIR in space! The toes and heels have extra padding for strategic cushioning to maximize absorption. They are made of stretchy 98% polyester and 2% spandex dual-blend fabric with reinforced toe caps.
