From the Manufacturer
Pearl iZUMi PURE run is what happens when you re-think the running experience from the ground up. A starting point not rooted in '70s folklore or industry dogma, but in simply creating better running products. The Pearl iZUMi design process has no constraints based on that's-the-way-everyone-does-it thinking or complex techno mumbo-jumbo. Pearl iZUMi PURE run is simply a better way of designing products. All Pearl iZUMi products are created based on a philosophy of no complexity and no compromise. The result is out-of-the-box comfort you can see and feel. This is PURE run.
