Versatile enough to handle anything from daily hikes to ultramarathon racing, the GEMRS is created to adapt to any trail running workout. At the heart of this versatility is a midsole made from Saucony's lightweight PWRRUN PB foam, which offers a lively ride while providing well-cushioned protection when tackling rough trails or long distances. Underlining the midsole is a 3-piece PWRTRAC rubber outsole that offers confidence-inspiring traction and grip for even the most technical of trails. Finished off with an engineered mesh upper for a breathable and comfortable fit, the GEMRS is a versatile and well-cushioned workhorse made to tackle any outdoor adventure.
