Sock ons are a simple yet highly effective solution to the problem of keeping socks on! Resembling something like a ’sock jacket’ Sock Ons slip on over the sock & ’lock’ it into place. The design lies in the fact that if the sock is pulled from the toes the sock gets locked into the hole around the heel thus preventing it from slipping off. Sock Ons make a perfect present for babies as well as being a must-have for every parent.
