The Altra Experience Flow 2 Review & Lab Test: Shop Men’S & Women’S Models of 2026

The Altra Experience Flow 2 is a lightweight daily trainer designed for runners seeking enhanced performance. Lab tests indicate that the shoe is ideal for those looking for a natural feel underfoot, evidenced by the new EGO P35 foam which offers a firm yet responsive ride. The measurement of the wide toebox ensures sufficient room for toe splay, promoting comfort during runs.

Despite these strengths, durability presents a challenge, with lab data suggesting that it may not withstand extensive use over time. Additionally, limited airflow could affect comfort during hot-weather conditions. Overall, the Altra Experience Flow 2 provides a unique balance of speed and comfort, making it suitable for daily training sessions.
