SIDAS Japan, handling a global insole brand, forms a partnership agreement with Teikyo Nagaoka High School Boys' Soccer Club

SIDAS Japan Co., Ltd. (Headquarters: Yokohama, Kanagawa Prefecture; Representative Director and President: Hiroaki Sugiyama), which develops and sells sports products from France supported by many top athletes, is pleased to announce that it has signed a partnership agreement with Teikyo Nagaoka High School Boys' Soccer Club for the April 2026 season. This is the first time SIDAS Japan has formed a partnership with a high school.

**Background of the Partnership Agreement**

SIDAS Japan and Teikyo Nagaoka High School Boys' Soccer Club have maintained continuous communication through trainers. On-site, many players use SIDAS insoles, and understanding of foot conditioning was widespread. Furthermore, positive feedback has been received from players using insoles in their daily activities regarding reduced foot burden, improved stability during play, and maintenance of conditioning, recognizing their usefulness through practical experience on the field.

On the other hand, young athletes in their growth phase are at a stage where foot burden and disrupted form can easily lead to injuries due to their developing bodies. SIDAS Japan has been active with the desire for these young athletes to incorporate insoles as part of their daily conditioning.

Our company has previously supported young athletes' feet through initiatives such as launching the junior sports support program "SIDAS Cup" and releasing soccer-specific insoles focused on the feet of growing children. This sponsorship is positioned as an expansion of these efforts to the high school age group.
