3sixteen x Chup Socks - Indigo, Pink. We can't say no to these. Two of our favorite brands teaming up is a dream come true. We're so happy they took the Chup technology and made some unpatterned styles. This first combo of Indigo and Pink is simply gorgeous. Each sock is knit with two different colored yarns whose placement and paneling are different between each sock in the pair. Each sock is made on Chup's vintage sock-knitting machines, and all heels and toes are hand-linked for a seamless finish.
