The shoe's last is shaped to accommodate a natural foot splay upon landing, shoes for fast running.

Nucleo 2 GR is the new all-terrain shoe for running on various surfaces, such as gravel roads, grass or clay surfaces, and light trails. The tread design offers greater grip, but is not so deep as to allow stones or debris to become embedded. The upper features denser, reinforced mesh, yet is still breathable.

The engineered knit upper adapts to foot swelling during long runs, maintaining consistent comfort without constriction, running shoes for low arches.
