Build quality is praised, with high-quality mesh, reinforced overlays, and a firm heel counter. Outsole rubber is strategically placed for longevity, and most reviewers report good wear patterns over hundreds of miles. Some minor concerns exist about the price-to-durability ratio, but overall longevity is above average for the category.
The On Cloudstratus 2 is widely regarded as a maximalist road running shoe with dual layers of Helion foam, providing substantial but relatively firm cushioning. Expert reviews consistently highlight its suitability for daily training and long runs due to its comfort, durability, and stable ride. The shoe's moderate flexibility and firm ride make it less ideal for tempo runs or racing, where lighter, more responsive shoes are preferred. Its weight and lack of aggressive propulsion further limit its racing suitability. The Cloudstratus 2 is not designed for trail use, lacking the necessary traction and protection for technical terrain. For recovery runs, the ample cushioning and stable platform offer a gentle ride, though the firmness may not appeal to those seeking a plush, soft feel. User feedback and expert consensus align in recommending the Cloudstratus 2 primarily for daily mileage, base building, and longer road efforts, especially for runners who appreciate a firmer, stable shoe.
Ideal for Best suited for intermediate to advanced runners with a neutral gait who prioritize support and durability for long road runs or marathon training. Ideal for those who appreciate a firmer, responsive ride and do not require a wide toe box. Runners seeking a reliable daily trainer for both steady mileage and occasional faster efforts will benefit most.
The Cloudstratus 2 is praised for its step-in comfort and adaptable fit, especially for runners needing more forefoot space. The upper is soft and wraps the foot well, while the midsole provides a balance of softness and responsiveness. The shoe is best suited for neutral runners seeking a plush, stable daily trainer for long distances. No carbon plate is present; propulsion comes from the Speedboard. Some users with very narrow feet may find the forefoot too roomy.
Sizing: Generally true to size for most runners. Some users with wider feet appreciate the broader forefoot, but those with very narrow feet may find the fit slightly roomy. No consistent recommendation to size up or down; fits similarly to other On models but with a more accommodating toebox.
