7pk Trainer Socks

One of the biggest fashion faux pas has to be an unwelcome sock popping out the top of your flats, right? Keep a stash of these seamless footies in your underwear drawer and they're bound to save the day more than once a week. This multipack includes five pairs of pop socks that are invisible when wearing shoes, so you don't have to worry about the dreaded VSL (visible sock line!). Top tip: keep a pair in your handbag, you never know when they might come in handy!
