These socks have a hidden zippered pouch that is wide enough to hold a passport, allowing you to secure vital travel documents and cash while keeping your pockets free. The nylon zipper will not set off metal detectors, and the pouch will not chafe the skin. Non-slip tops keep the socks at mid-calf level, and a cushioned toe and heel sections made of combed cotton eliminate blisters. A breathable Holofiber footbed helps to reduce swelling by increasing oxygenation, and the flat toe seam won't rub against the top of your foot. One pair. Imported. Tan or Black. Mens size M (5-8) or L (8-121/2) or Womens size M (6-9) or L (9-13). 10" L x 3 1/2" W. (6 1/2 oz.)
