Best Answer:Thank you for your question. Our Jockey 360 Stretch Crew features a comfortable fit along its upper edge. There should be no binding or tight feeling, but that elastic should still be strong enough to ensure that your socks aren't slipping down. If you ever run into a problem with these or any other Jockey product, please do not hesitate to let us know at 1-800-JOCKEY-1 (800-562-5391). If there are any other questions we could answer for you, please let us know!
Best Answer:Hi, thank you for your question! I am very sorry but we do not have a sock that covers a shoe size 13. Our socks cover men's shoe sizes 7-12. I will suggest to our product development that we make our socks in larger sizes in the future.
