Retail price: 22,000 yen Description: This is a top-of-the-line LONG walking model featuring an energy-saving structure specifically designed for walking. Energy-saving structure: The technology packed into the curved sole reduces ankle flexion during walking, thereby reducing energy consumption in the ankle joint (around the calf) and improving walking efficiency. The upper pattern design incorporates eyelet placement to enhance fit, based on research conducted at the ASICS Institute of Sport Science. Additionally, seamless parts strategically placed inside the shoe efficiently transmit tension to the upper, enhancing the overall fit of the shoe and supporting more comfortable brisk walking.
