You are correct, they do normally call for more yarn than lady's sock patterns! Have a look at my site
if you would like, there are a couple that don't require as much yarn, Mock Around the Clock took a bit less than a ball of Opal; Music Man took less than a ball of TOFUtsies; and Lonnie's Sport Socks took a 2 - 50 gr. balls of KnitPicks yarn.
Those are all that I have for the amount that you require (fyi, on size 11 foot) but you can also check on www.knittingpatterncentral.com
, too...she has LOTS of patterns!
