This pair of socks is the slip stitch basic heel from the book, Socks from the toe up by Wendy D Johnson. I changed the instep and the leg of the sock to a k3p3 rib. I love them. I’m still trying out different heels to see which I like best. This heel had wraps and turns that the gusset basic sock did not have. The way it wears is 
a concern. From what I hear, the slip stitch heel can better withstand the rubbing/friction from the back of a shoe. We shall see. This yarn was glorious to knit with. It is Bittersweet glamour glams HT. Hand dyed superwash sock yarn. Content is merino/cashmere/nylon. Colorway is Avalon. I purchased it at the NYS sheep and wool festival in Rhinebeck, NY.
