Pocket SocksFashion Dress Socks for Men and Women, Hidden Zipper Security Money Storage for Business, Travel, Keys, Cash

Great for peace of mind during travels. There was enough room to fit emergency money in the storage pocket. They not only held up during the trip but have endured 6 months of regular wear and washing cycles since then.I recommend sizing up if you are on the larger end of the size range. I agree with other reviews stating that the sock can get tight when items are added into the pocket.

Very comfortable.

These are perfect for travel. Credit cards and money fit in the zipper compartment. The socks fit really well and are made really well, too

I received a three-pack of black socks and wore them in sketchy areas during travel in South America. As others stated, the pocket is just barely large enough for a credit card. Material was not heavy so they were not too hot to wear in the summer. Only downside is if you should ever take off your shoes in front of others: the label "Pocket Socks" is boldly printed on the toes. I wore them through a TSA screen machine, the kind wear you put your hands over your head, and the TSA man scanned my ankles since the machines apparently detected something from the Pocket Sock pocket.

I didn’t use it. It was a gift for someone else.
