Finding dress socks in stores for a size 13 foot is just about impossible so I turned to Amazon and found these and happy days are here again...well.....at least for my work clothes anyway. These fit perfect, not tight at all and plenty of room. In fact I like them so much I bought a 2nd 6pk just to have on stand by but I do have one important recommendation, DON'T DRY'EM IN THE DRYER! These will shrink as I found out the hard way.
