Do nike elite socks run big?

They are made for specific shoe sizes so if you are a 6-8 mens shoe size you should get medium or if you have 8-12 you should get large or 12-15 size is extra-large. for women's size 6-10, you should get size medium or if you have smaller feet than that get small. They don't run big but if you do wash them and then dry them on high heat, they will shrink a bit.
