I wear a size 12 so I ordered XL which according to the sock size chart fits 12-13.5. I could barely get my socks over my feet and figured the fit would be hopeless for someone over 12ft. The material is much less "stretchy" and breathable than most socks, so I felt like my feet were in rubber gloves that were too tight. I think if the sizing is right it could be good in terms of support. These socks seem to be rated highly by most reviewers - that's beyond me based on my experience.
