Here's a pattern I'm quite happy with. Mainly the chart and the colorwork. I wanted something fairy taleish and this is what I came up with. I used mainly stock yarns, left over bits, 10 different color in total.
Size wise these may not be the most practical ever, the pair I made would ideally fit someone with a size 39 foot and a very slim leg. For me the socks are snug around the calf and ankle and required some blocking. But here's the charts and rough instructions anyway, feel free to modify as you see fit :)
Instructions:
The socks are knit top down. Chart is read from top to bottom and divided in 2 columns for an easier read and possible printing. 
Size: EU 37-39 (7-8.5 US, 5-6.5 UK) (may vary by your gauge) I'm a size 39 with a wide calf and these had to be stretched out to fit my calves, prepare for a very snug fit.
Yarn: Novita 7 veljestä (150 g = 300 m, 75% wool / 25% polyamide)
Gauge: 23 st = 10cm
Needle: 4 mm
Cast on 56 st. Divide them on 4 double pointed needles, 16st on each needle. *Knit 1, purl 1* for about 6 rows. Begin working as per chart repeating the 28 stitch pattern. The chart is read from bottom to top. When you reach the blue line at the top of the right hand column, make reinforced heel as per instruction or any heel of your choice, then continue the chart from the bottom of the left column.
Reinforced heel:
Once you reach the mark for heel knit (dark green) on needles I, II and III and then leave needles II and III waiting to be worked on later. Begin reinforced heel on needles IV and I. *Slip 1 knitwise and knit 1* and repeat this for all stitches on needles IV and I. Then turn to the the wrong side of the sock, slip 1 purlwise, purl 31. Repeat these two rows 14 times = 28 rows.
Then on the right side (still knitting slip 1, knit 1 on right side and purl on wrong side) knit until you have 10st left on the needle, slip one, knit one, pass slipped stitch over and turn to wrong side. Slip 1 purlwise, purl 8, purl 2 together and turn to right side. Knit in this manner until you have 10 stitches left total on the heel. Divide the remaining stitches on two needles. Continue in dark green and pick up 13 st on the side of the heel flap on needle I, knit needles II and III, pick up 13 st on the heel flap again on needle IV.
The gusset:
You now have 64 stitches in total. Continue working the chart from where we left off (heel mark). Knit 2 together at the end of needle I every second row and slip 1 knit 1, pass slipped stitch over at the beginning of needle IV every second row until you have 14st on each needle again. Note that the pattern on the decrease rows will disrupt at the decrease points but work the rest of the stitches according to chart. Continue according to chart.
Shape toe:
Once you've reached row 92 begin shaping toe.
At the end of needles I and III; knit the third and second to last stitch together and knit 1. At the beginning of needles II and IV knit 1, slip 1, knit 1, pass slipped stitch over. On the remaining stitches knit a checkered pattern as per chart. When you are left with 3 st per needle cut the yarn and run the thread tail through remaining stitches twice; pull firmly and darn in the ends.
