The Wave Inspire 13 is constructed with a breathable and newly redesigned Airmesh upper to promote better airflow and dexterity, while the generously-sized heel provides a locked-in (not to mention an in-control) fit and feel. Additionally, the U4icx midsole not only attenuates shock, but provides an energetic bounce back, so you're able to launch through transitions and make the most of your stride. The blown rubber at the forefoot offers ample cushion lest you begin to feel the bonk, and the sole maintains traction and added durability.
