The Nike Legend Essential 2 comes equipped with a flat, stable heel, flexibility under the toes, and side-to-side support. With tons of grip, you're ready to lift, HIIT conquers a class, or get stronger on the machines. The design helps brace your heel on top of a flat sole for stability during lifting and squats. Rubber wraps up the outside for support when moving side to side. Grip That Keeps Going. Grooves in the sole under the toes keep it flexible for push-ups, planks, and agility drills.
