This is a new pattern of mine, using an afterthought heel but with a gusset of sorts. They are very comfortable with no digging in or strangling of the foot. Great pattern for hand spun, wildly variegated or self striping yarn.
The Marmolejo Socks are for sale at Ravelry! And I could use a test knitter or two, so if you are interested in getting the pattern for free, let me know.
