My next pair I plan on doing what's called a short rowed heel which will eliminate the chaining around the ankle which always give me this tight feel and doesn't offer much give around the ankle.
I finished these a few months ago just when t he temperatures soared up to the 100's. I didn't even want to put them on to take a picture!
Today they were the perfect thing to keep my toes warm on this cool fall day.
I used Sockotta sock yarn. I love how it feels.
