Nike Air Alaris+ 4 MSL

The Nike Air Alaris+ 4 MSL is a running shoe designed primarily to provide a stable ride and supportive fit. Improvements over the Nike Air Alaris+ 3 MSL include a durable TPU frame in the upper for stiffer support and better stability throughout the run cycle, and new flex grooves at the outsole for controlled flexibility and a more natural feel.

An EVA sockliner is also now included for increased comfort. Returning features include a mesh upper that allows for airflow and a crash pad for shock absorption and pronation control. The full-length Nike Air unit handles the cushioning of the foot along with Phylon at the midsole, and modified Waffle lugs at the outsole provide traction suitable for most surfaces.
