They really are the same length. I just can't take pictures upside down very well.
Pattern: Cable Twist modified for fingering weight yarn
Yarn: 2 skeins Koigu KPPM colorway #2233
I love this pattern for fingering weight yarn. I may have to try it in worsted weight for the winter months. The yarn has a nice tight twist and doesn't split. it got a little fuzzy after frogging, but that's to be expected. I think the colors are nicely saturated, and I love the way it's not completely solid. I can't say I would use it again because for the price, the yardage is a little skimpy. I didn't run out of yarn, but I also didn't make them as tall as I was hoping to.
My changes (some stolen from other people):
I made it over 64 stitches with each repeat being k6p2. One sock has the cables twisting to the right while the other goes to the left. I used an eye of partridge heel.
