Launch of a New Model of Assist Insoles

MEDIAID, a dedicated supporter brand by Japan SigmaX, is set to unveil a new type of assist insole, the "Assist Insole Arch & Grip Electrostatic Discharge Prevention" on March 2, 2026. This innovative product is tailored for workplaces where wearing shoes that prevent static electricity is essential.

Addressing the Concerns of Workers Wearing Safety Shoes

In various industries, including manufacturing and logistics, companies often require employees to wear safety shoes to ensure their safety. Recognizing this need, MEDIAID utilized its expertise in developing insoles for sports to create products that alleviate the challenges faced by workers donning safety shoes. In 2025, the "MEDIAID Assist Insole Arch & Grip" was released, which gained popularity, surpassing sales of 25,000 pairs within less than a year.

Following the successful initial release, the company received numerous requests for insoles designed with electrostatic discharge prevention features. In response to this demand, the brand is now adding static electricity suppression capabilities while maintaining the original features that garnered praise with the launch of the new model. Through this product, MEDIAID aims to support the feet of those working in manufacturing and logistics sectors who wear safety shoes.

Key Features of the New Electrostatic Discharge Prevention Insole

1. Static Electricity Suppression: Conductive threads are incorporated into the forefront of the insole, ensuring it's effective in preventing static electricity. Note: Must be used with safety shoes designed to prevent electrostatic discharge.

2. Unique 3D Design Based on Windlass Mechanism: This design appropriately supports the foot's arch, guiding it to an ideal balance that reduces the strain on the feet.

3. Flexible Holders that Adapt to Foot Movements: The flexible holders in the insole conform to the movements of the feet, providing a comfortable fit.

4. Superior Grip with Anti-Slip Topcoat: The surface uses a non-slip material that enhances the sense of unity with shoes, also featuring antibacterial and deodorization properties.

Understanding the Windlass Mechanism

The Windlass mechanism sees the toes lifted, causing the plantar fascia to become tense and elevate the arch of the foot. This action results in propulsion during walking, enhancing ease of movement.
