Fibrillation resistant uppers maintain structural integrity under tensile stress

The personal relationship you have with the Peg is unlike anything else. Faithful. Reliable. The pair thats always there, pushing the running world forward, while still putting your wants and needs first. With an always speedy Zoom Air engine on top of softer, more responsive ReactX foam the Pegasus 41 is quietly unlike any other Peg we have ever made before. A springy ride for any run, better for all runners on this planet, and all planets where we run.

This style adapts to weather adaptability
