ZOOT built its reputation on making race and training gear for the unique needs of triathletes. As such, the Men's Race 4. 0 Running Shoe is a lightweight, neutrally cushioned shoe that's fast through stage transitions and even faster over the pavement. The flexible upper slides onto your foot quick, the BOA lacing system dials in the fit with a twist, and the energetic midsole construction propels you forward off your toes. Every detail in this shoe is purpose built to help you perform when the miles are long, your feet are wet, and seconds count.
