This is the most beautiful superwash i have ever used. It feels beautiful to knit with and it holds a stitch firmly, which makes it perfect for these socks. When i first brought these to class the other knitters were skeptical, but after trying them on they agreed it’s all in the fit. The top drapes gently around your arch, allowing the ball and heel of the foot to rest (not grip, there is no gripping in yoga!) Directly on the floor.
