Kids just love playing games and the more action the better. And while we may wish they'd spend all their time outside climbing trees or making kites like children did in the old days, the fact is that blasting aliens or racing fast cars is cracking good fun! And the great thing about our Sock Invaders is that they can be worn all day without any ill effects whatsoever. Game on! These socks are made of: 76% Cotton, 23% Polyamide, 1% Elastane.
