Purchased from Stride Lab in July 2025. Color is SAND. It's the latest model. The color is natural and very beautiful, easy to match. Used a few times. There are no major noticeable stains or scuffs, but there are some small stains due to the light color. The soles show almost no wear. With a 4mm drop, it's recommended for those who are uneasy with zero-drop shoes. It has great cushioning and is less tiring. This 22,000 yen item is sold out. Don't miss this opportunity! The "Experience" series, "Experience Flow 2," has been updated. This series, positioned as a transition shoe before getting used to ALTRA's 0mm drop, has been constantly evolving since the 2024 season. This model maintains the basic performance while further improving comfort with the adoption of a heel collar that enhances the fit and a more breathable engineered mesh. While retaining ALTRA's familiar spacious "FootShape design," the midsole features the newly developed "Altra EGO™ P35" midsole foam, pursuing lightness, performance, and comfort. The combination of a low drop and rocker shape enables efficient toe-off and a smooth stride, supporting a natural transition. The introduction of this low-drop model, "Experience Flow 2," will broaden runners' options and help them find the perfect shoes for themselves. The sizing uses the "Standard" FootShape, and although the fit has improved due to the design change of the heel collar, the sizing is almost the same as the previous model. For example, a staff member with a right foot length of 28.3cm / left foot length of 27.9cm and a foot circumference of right 26.4cm / left 26.0cm wears US11.5 and can wear it comfortably with the same sizing as the previous Experience Flow.
