Made for all young, aspiring Avengers, our kids’ SOCKSHOP Heat Holders Marvel\'s Captain America Shield Slipper Socks are cosy in a thick, bright blue knit, with a representation of the Captain’s iconic shield at the top, and repeated as a series of clever anti-slip treads on the soles. These heroically super-soft, super warm socks have all the thermal super powers of our famed Heat Holders socks, with plush soft brushed inners that catch and trap warm air in the long fibres, effectively shielding feet from the cold.
