Gold ToeMen's Socks (Pack of 3)

Are these as thick as the gold toe uptown crew sock?

Are these over the calf socks? Also do they fall down?

Are these very stretchy especially in toes, as I can't take the spandex causing socks to pull back tight on toes as putting on shoes tends to do?

Would these "extended size" socks fit a wide 10-11 shoe size foot?
