About the Saucony Endorphin LD 'Mutant'

The Saucony Endorphin LD 'Mutant' delivers a performance track spike that utilizes a breathable white mesh upper. The lightweight build is mounted on an anatomically shaped last, featuring a broad platform for a blend of stability and propulsion. A full-length carbon fiber plate enhances the IncrediRun midsole, made with a high-rebound, low-density foam that yields ultra-responsive cushioning.
