The socks are of exceptionally high quantity and i initially ordered in large as my feet are 11 in shoe size. But when i received the socks i found them to be little too big for my feet. So i contacted customer service and they were really very much helpful and graceful to send the all the socks in the same quantities but with medium size. I really appreciate the customer services- Ann excellent in understanding the situation and sent me all the sock immediately. Thanks for prompt customer service. Only thing is I recommend making the site more user friendly to order and initiate returns when necessary. Thanks, Bhaktavatsalam Gani
