(Another type of heel would be the yo-yo heel, ... maybe I'll try that one later ...)
So, these short socks use the sweet tomato-heel technique by Cat Bordhi (http://catbordhi.com/) and a stitch that's called coffee bean pattern (Kaffeebohnenmuster).
This is not a complete pattern, but just a rough sketch.
- Tomato Heel: http://www.youtube.com/watch?v=IRc3309JUyc . In short, the heel is constructed of three short row wedges.
- The "Coffee Bean Pattern" consists of 4 rows.
Row 1: p1 k2 p1
Row 2: p1 k1 yo k1
Row 3: p1 k3 p1
Row 4: p1 sl1 k2 psso p1
- Toe decreases, as described in this Knitty article (http://www.knitty.com/ISSUEspring05/FEATsocks101.html, section 9) or shown here: http://www.youtube.com/watch?v=j4bEhqXgOIU
With 3.25mm needles CO60
With 2.5mm needles knit 10 rows of ribbing
Switch to 3mm needles and knit 3 sets of coffee bean pattern
Knit tomato heel (while knitting the full rounds, continue coffee bean pattern on the front third)
Continue the foot, knitting coffee bean pattern on the front third and stockinette on the backside (2 thirds).
When foot is long enough, do toe decreases and graft leftover stitches.
