Development Background
In recent years, the prolongation of summer has led to a significant rise in September temperatures. The average temperature exceeds 26 degrees Celsius, and the maximum temperature can approach 35 degrees. In particular, the ground surface can exceed 60 degrees Celsius in summer, making measures against foot heat essential.
In this context, 'Foot Cool Biz'*3, which involves wearing short socks to expose the ankles and keep cool, is effective.
However, short socks often come with problems such as 'they slip off easily and are troublesome to put back on' or 'they shift with every step, causing stress'. The 'Non-Slip Kokopita' was developed to solve these slipping issues.
To address various problems faced by feet in summer, the 'Non-Slip Kokopita Cool Type' was developed using a contact cooling fabric that is perfect for 'Foot Cool Biz'.
Furthermore, the 'Cool' Kokopita has been evaluated not only for its non-slip feature but also for its other functions, achieving a 93% post-wear satisfaction rate!*4
With its 'cool' and comfortable fit, it supports keeping your feet cool in summer.
