As a mother of three I have to say I LOVE LOVE LOVE the Goldtoe sizing system! The number of gold rings around the toes indicates the size! No more confusion about whether these socks belong to baby #2 or baby #3! My daughter loves the colors and designs and I love that this is the same brand of socks her dad has been wearing for 20 years so (please forgive me for sounding like an advertisement) I know I trust this brand .
