SIDAS Japan Co., Ltd. (Headquarters: Yokohama, Kanagawa; President: Hiroaki Sugiyama), a developer and distributor of sports equipment 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 marks SIDAS Japan's first partnership agreement 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 the field, many players favored SIDAS insoles, and an understanding of foot conditioning was well-established. Furthermore, positive feedback was received from players using insoles in their daily activities regarding reduced foot burden, improved stability during play, and maintenance of condition, recognizing their usefulness in practical terms.
On the other hand, young athletes in their growth phase are particularly susceptible to injuries due to foot strain and improper form, precisely because their bodies are still developing. SIDAS Japan has been active with the desire for athletes of this age group to incorporate insoles as part of their daily conditioning.
Our company has previously supported young athletes' foot health through initiatives such as launching the junior sports support program "SIDAS Cup" and releasing soccer-specific insoles focused on children's growing feet. This sponsorship is positioned as an expansion of these efforts to the high school age group.
Details of Support

Moving forward, we will contribute to enhancing the daily training environment and creating better conditioning by providing support tailored to each player's foot condition and athletic characteristics.
