This rendition of the NOOSA TRI™ 13 shoe is designed with various details affiliated with Boston. The heel graphic of runners running past the town’s skyline is complemented with a patriotic color palette. Meanwhile, the sockliner features different caricatures that pertain to everyday life in the city. With GUIDESOLE™ technology underfoot, this shoe reduces ankle flexion and the load placed on your legs. Its curved sole helps your legs feel fresher while experiencing a smoother stride. FLYTEFOAM™ cushioning in the midsole is designed to increase shock absorption. It’s a soft and lightweight material that makes the shoe practical for tempo runs, long training runs, or racing.
