This product is a model with the clear benefit of being "shoes that help children run faster." In effectiveness verification tests, 78% of children who wore them improved their 50m sprint times*, providing results that support their functionality. Additionally, the series released in July 2025 received a significant response, selling out immediately upon release. This model is a limited-edition 100th-anniversary version developed in response to that popularity.

[What is SUPERSONIC?] ~Shoes that fulfill a child's wish to 'run faster'~ Equipped with a high-rebound plate designed to match the running characteristics of children, these shoes achieve a cutting-edge structure that is rare for children's footwear. Furthermore, by adjusting the thickness of the plate in 0.01mm increments, the shoes support natural running without hindering growth.

Designed to maximize rebound force, they demonstrate high performance in scenes where instantaneous power and speed are required, such as field days, short-distance races, and physical fitness tests.

[Limited edition model commemorating the 100th anniversary] The 100th-anniversary model adopts the "TGF dial system," which allows for fit adjustment without the use of shoelaces.

It can be easily put on, taken off, and adjusted simply by turning the dial, allowing for stress-free use. The excellent fit, which feels like an extension of the foot, provides a comfortable wearing experience.

Additionally, an original 100th-anniversary knapsack is included. It is a special specification that is convenient for carrying the shoes as well as for daily use.
