Breathable mesh upper has a wider forefoot construction, allowing for increased toe splay and a more natural, powerful stride. Dynamic arch band works with Flywire cables, wrapping the midfoot and delivering supportive lockdown over the footbed that can be adjusted through the shoe's laces. Cushlon midsole for lightweight, responsive cushioning with every step. Rubber is removed in the midfoot, exposing a portion of the midsole for increased flexibility, lighter weight, and reduced debris from the course. Lugs are placed strategically around the outsole's perimeter, delivering aggressive traction and explosive speed. Wt. 4.6 oz.
