HanesMen's 6 Pack Over-the-Calf Tube Socks, White, 10-13 (Shoe Size 6-12)

do they fit men with big calfs

How many pairs are in a "Pack"???????

Six pair or just six socks (3 pair)?

Are these really tube socks, or do they have heels? I see tube in the name, but I bought a different type of Hanes "tube" socks, and they had heels.
