The premium bamboo fabric used to make i hate socks' has a gentle stretch that's optimal for most kids - not too loose, and not too tight.
The innovative heel free design means the socks are shaped like a tube, making them very easy to pull on without any bunching up. It also means that sizing is very flexible, so each size covers a generous range of feet sizes.
They are designed to be crew socks, sitting just above the ankle. If you're after a longer sock, go for a larger size. If you prefer a shorter sock, size down.
This goes for ANY size foot - yes, our socks comfortably fit adults too!
Can't decide? Go for medium - it's a pretty universal.
