Push yourself farther than ever when you run in the Saucony Zealot ISO running shoe, Saucony's most dynamic, foot-hugging trainer yet. Plush and lightweight, this neutral men's low-profile sneaker has an ISOFIT synthetic and mesh upper to deliver a sock-like feel. The Support Frame™ adds structure and support in the heel, while a full-length PWRGRID+ midsole provides 20% more cushioning than the previous version for enhanced impact, protection and enhances durability. An outsole that combines iBR+™ (blown rubber) with XT-900™ rubber offers improved durability. Reflective details at the heel increase visibility in low-light conditions.
