Men's US10 (28.0cm). The following is quoted from the HP: Max cushion shoes, perfect for long-distance, long-duration running and walking. Equipped with the newly developed supercritical foam midsole "ALTRA EGO™ FLO," achieving the highest level of cushioning. The supercritical foaming technology also provides excellent lightness, maintaining a comfortable fit and cushioning even during long hours and long distances. In addition, the design intentionally suppresses resilience, allowing anyone to experience a stable fit. The 4mm low-drop design complements the rocker shape of the shoes, creating a natural forward-moving sensation with every run and walk, supporting efficient toe-off. The upper features "Engineered Spacer Mesh" with a sophisticated design and excellent breathability. Furthermore, ALTRA's signature widest original foot shape naturally frees the foot, providing a free and comfortable fit.
