Adizero Boston 13 / ADIZERO BOSTON 13 adidas Adidas 27.0cm New, unused, but the box has been discarded. The midsole continues to feature the full-length, five-finger glass fiber rods "ENERGYRODS 2.0" adopted in the previous model. In addition, the adidas' proprietary low-density, high-rebound material "LIGHTSTRIKE PRO" has been increased by 13.8% compared to the previous model. This achieves a high level of cushioning, resilience, elasticity, and lightness, while providing a softer and more comfortable feel underfoot. Furthermore, the new outsole "LIGHTTRAXION" introduced in the top racing model "ADIZERO ADIOS PRO 4" has been newly adopted, providing high grip while reducing weight. The cushioned tongue and opening have been adopted, and the touch around the instep has been adjusted for greater comfort compared to the previous model.
