Reports from Running Shoes Guru and Fleet Feet indicate minimal wear after 100+ miles, with build quality and materials holding up well. There are few complaints about premature breakdown, suggesting above-average durability for a lightweight trainer.
The Asics Noosa Tri 13 is widely praised for its lightweight build, aggressive toe spring, and firm yet responsive midsole, making it especially well-suited for tempo runs and race efforts where a snappy ride is desired. Its breathable, comfortable upper and roomy fit support longer distances, and testers found it durable and accommodating for marathon training and long runs.

However, the firmer ride and lower drop make it less ideal for pure recovery runs, where softer cushioning is often preferred. Traction is noted as a weakness, limiting its suitability for trail running or technical terrain.
Ideal for Best suited for intermediate to advanced runners or triathletes who prefer a firmer, responsive shoe for tempo runs, long-distance racing, or brick workouts.
