Socks with the healing power of a Japanese hot spring.

Made with Integrated Functional Mineral Crystal (IFMC) technology (Patent no. 6557442) by Teikoku Seiyaku Co., Ltd., inspired by traditional onsen therapy in Japan. IFMC are nano-level, fine mineral crystals made by combining natural minerals, soaking them in iron-rich hot spring water, and then applying a special extraction and processing method to produce a crystalline substance that stimulates the diffusion of nitric oxide from blood vessels, leading to their expansion and improving blood circulation for recovery and relaxation.

Collaborative research with institutions such as Kyoto University and J-PARC continues to explore its physiological effects and potential health applications.

Antibacterial and odor-resistant due to IFMC processing. Excellent stretchability, softness, breathability, and thermal insulation. Uses double-sided brushed yarn with the highest anti-pilling grade of 5 for high durability.

Size: 22-27 cm
