Charlene Schurch's book "Sensational Knitted Socks". It is the beaded rib. It's easy to follow. Short row toe was a little daunting but I hate wrap and turn short rows anyway. The yarn is from KnitPicks, Flyfishing. The person I am making these for have HUGE feet. I hate making socks anyway because it takes so long and it can be tedious. Plus I have to hold the tension so tight it hurts my index finger. So I have set these aside for now and am making some Fetching fingerless mitts for other people (including myself).
