I've knitted these socks as faithfully as possible to the design by Mr. Rokugo. The entire sock is knitted with three strands of fingering weight wool yarn (100% wool) held together. Finished size is 22cm. Since it's knitted, it will stretch, so it should fit someone with a foot size of about 24cm. The ankle measures 22cm when finished. There is no tightness. For the heel, I added one more strand of fingering weight yarn, using four strands held together, and knitted it in a way that makes it durable and provides good cushioning. The ankle is shaped with decreases and increases to make it fit comfortably. The colors in images ③, ④, and ⑦ are the closest to the actual color. I knitted these carefully with good quality yarn, but it's a hobby project. This is a hobby knit. It is not perfect. I hope those who understand this will consider purchasing.
