Have you ever examined a spider web up close? Its intricacies. Its negative spaces. Its ability to wrap and hold things. Our designers have. The PUMA BioWeb Elite is a running and training shoe engineered to deliver maximum cushioning and stability. It wraps the foot with an innovative WebCage design that delivers a fresh new look in performance: injected PU overlays with a high strength-to-weight ratio offer lightweight and flexible support that doesn't compromise durability. And, carrying the unique design language into the actual tooling, WebTech, a flexible TPU heel wrap, provides impact protection without sacrificing cushioning.
