Experience the soothing, restorative comfort of socks infused with the "healing power" of a Japanese hot spring. Developed using Integrated Functional Mineral Crystal (IFMC) technology (Patent No. 6557442) by Teikoku Seiyaku Co., Ltd., this innovative material is inspired by traditional onsen therapy.
IFMC consists of nano-level mineral crystals created by combining natural minerals with iron-rich hot spring water, then extracted and processed into a fine crystalline form. These crystals help stimulate the diffusion of nitric oxide from blood vessels, promoting gentle vasodilation and improved circulation - supporting recovery, relaxation, and overall wellness.
Ongoing collaborative research with institutions such as Kyoto University and J-PARC continues to study its physiological effects and potential health applications.
The socks are designed for comfort and performance: antibacterial, odor-resistant, highly breathable, and exceptionally warm. The double-sided brushed yarn achieves the highest anti-pilling grade of 5, ensuring durability while maintaining softness and stretch.
Product Use
Suitable for daily wear, rest, and post-activity recovery. Simply wear as normal socks to enjoy their circulation-supportive and warming effects.
Precautions
• Do not use on irritated or damaged skin.
• If discomfort or irritation occurs, discontinue use.
• Avoid high-heat drying; wash gently to maintain IFMC performance.
• Keep away from open flames.
• Store in a clean, dry place.
