I am 6'3" 205 with a size 12 foot. I like knee socks to work out and run in, but finding good ones that go to the knee is tough. The Eastbay Evapor line is about the best I have found but the styles are dull single color only. I purchased this Moxy sock along with one from Gumball Poodle at the same time. The price was also about the same. The Moxy sock is far superior. If you read my review for the "ninja" Gumball Poodle sock, you will notice my chief complaint was that it was about 2" short. The Moxy sock has that extra length, which for me brings the sock up to the knee. The Moxy sock is also a thicker material and seems more robust in general. The Moxy socks would offer some protection for the lower legs when lifting. They also aren't bad to play sports in or run in as long as the temps are to hot.
