Two-tone socks from Japan in a seasonal palette drawn from the spring flora of mountain villages. Based on the structure of medical support socks, they are knit using a three-layer construction: an outer yarn, middle yarn, and inner yarn. The combination of these layers creates a gently supportive fit without elastic, allowing circulation to remain unrestricted while minimizing friction and adapting comfortably to temperature changes. A subtly angled heel encourages the sock to sit securely on the foot and reduces slipping. Made in Japan by Sarigenaku.
