Have you heard of this new trend of putting copper in socks, supposedly for health reasons? To us, those benefits seem pretty nebulous. But there’s one thing copper-infused socks have been proven to do: kill odor-causing bacteria on contact.

Which, honestly, is enough of a benefit for us. Who wouldn’t want to be able to kick off their shoes after a long day at work or a sweaty gym session without clearing the room with their stinky socks?

Of course, because these are compression socks, they are associated with some pretty significant health benefits: they’ve been shown to reduce inflammation and help keep your muscles from feeling sore and achy when worn after a workout. They’re also a must for long plane rides, reducing the risk of leg swelling or developing blood clots.

So there are plenty of reasons to pick up a pack (or more) of these socks. This great deal is just one of them.
