New 'Ashiwuraku' Socks Launched to Support Foot Health for the 70% of Japanese with Fallen Arches

Medical device manufacturer Daiya Industry Co., Ltd. (Headquarters: Okayama City, Okayama Prefecture; President: Hiroki Matsuo) launched 'Ashiwuraku' on June 1, 2026. This high-functional sock focuses on the 'fallen foot arch' (low arch), a condition said to affect about 70% of Japanese people, allowing for professional foot care simply by changing daily socks. It supports those who feel heavy legs in the evening, experience tingling sensations in their feet from standing work, or have foot-related troubles.

Potential Risks for 70% of Japanese About 70% of Japanese are said to have 'low arches'. The foot arch acts as a cushion to absorb shock when walking. When this collapses, it can lead not only to leg fatigue but also to burdening the knees and lower back. Previously, mainstream methods for foot care included insoles, supports, and taping, but customers voiced concerns such as 'insoles limit the shoes I can wear' and 'taping risks skin irritation.' Therefore, the company realized daily care that is 'shoe-friendly, irritation-free, and affordable,' allowing everyone to continue every day.

Key Points of Ashiwuraku (1) Lighten Steps by Reducing Burden The special knit structure supports the vertical arch (instep) and absorbs shock to the soles. By aligning the arch, it reduces burden not only on the soles but also on the knees and lower back. (2) Stable Walking and Standing Posture Support for the lateral arch stabilizes the torso during standing postures. It balances weight distribution, supporting long hours of standing and stable walking. (3) Comfortable for Long Hours Instead of strong, one-directional pressure, it adopts a unique 'honeycomb structure' that applies pressure from all directions on a 'surface.' The fine-gauge knit provides natural pressure strength, ensuring long-term comfort with little discomfort. (4) Roomy Design for Easy Toe Movement The toe area is designed with extra space to support free movement of the toes. Because it's worn all day, the company insisted on a design that ensures comfort.
