Now vegan-friendly, your updated Men's Saucony Guide 15 reimagined everything that's ever been done in this series for the ultimate package of light, ultra-smooth comfort. A fresh PWRRUN formula lays on a thicker stack of cushioning that allows your foot to smoosh down for a soft landing and encourages a springy release with every toe off for the smoothest ride. Saucony went even further with the Guide 15 running shoes by carving out a deeper footbed in the midsole, removing any stiffness for a perfectly contoured and supportive fit.
