Hiya hun and welcome to the party.
Here are a couple links I came up with for ya, Hope this helps. If you wanted to make em longer you could just add more rows between the cuff and the heel shaping.
But if you want, I will write down the pattern for the sox I am knitting now for my hubbiness ( I've made them orthopedically correct ) I will post it on my blog for all to gander at. (I better get to knitting huh so I can take pics of em n post them and the pattern I used for them) He has huge feet, lost a couple of his toes in an oilfield accident, and has plantars fasciitus (bone spurs) not to mention he has enormous calves. So I hope this helps ya a bit. And I'll get right on that for ya
Happy knitting ya'll n let's get knotty!!
