Naigai Launches 'Cooling Socks' Series Featuring High Breathability for Summer Comfort

Overview Naigai (Headquarters: Akasaka, Minato-ku, Tokyo; President: Kenji Imaizumi) has launched the new 'Cooling Socks' series to realize a comfortable foot environment in summer. Focusing on foot discomfort during seasons with rising temperatures and humidity, the series achieves a dry and comfortable feel by utilizing highly breathable, moisture-wicking materials and specialized knitting structures.

Background In recent years, the need to reduce discomfort in the shoe environment has been growing due to rising summer temperatures. Sticky or stuffy feet are a source of stress in daily life and business, increasing interest in functional, comfort-oriented socks. Following the designation of days with temperatures over 40°C as 'extreme heat days,' this series was developed to support cool feet during summer.
