A comfy fit and the smoothest ride found anywhere, this Jazz 4000 features breathable mesh, synthetic suede reinforcements, molded EVA cushioning, and the iconic triangle sole traction. This special makeup for the Saucony X Boston Children's Hospital collection was inspired by Kieran. Kieran's story with Boston Children's started with his feet as he was diagnosed with severe bilateral clubfeet. Through treatments, surgeries, and recoveries Kieran has shown resilience. Kieran's inspiration for his designed Jazz 4000 comes from baseball and bold colors for an eye-catching sneaker.
