Launched by Achilles Corporation in 2003, the Syunsoku junior sports shoes garnered a tremendous following among children. The brand helps children fulfill their ardent desire to “run fast on sports day” and “not fall at the corner.” Syunsoku sought to construct shoes in such a way that would allow the runner to maintain speed by gripping hard even on corners where speed tends to drop, by employing asymmetrical soles with more spikes on the left side of the sole that bears the weight in track events.

Not only do the shoes now enjoy a high level of recognition and enormous popularity among children, they are also creating a sensation that could be regarded as a social phenomenon extending beyond the realm of sports shoes.
