I finished my Cat Bordhi Riverbed socks a while ago. The fit really well, I will definitely use that architecture again. After I washed them, it seems like the ankle and leg weren't as tight. I wonder if the washable wool + nylon grows. I've never taken a gauge reading after washing socks.
I used Trekking XXL and size 1 needles. I divided 52 stitches on two needles. I did a 3knit1purl ribbing around the leg and the instep.
