Built on the foundation of Reductionist Theory, the UltraRide First Mile Xtreme removes the limits with outsole cutaways to leave you with one basic running essential: cushioning and responsiveness for limitless potential. A light upper and supportive midsole plate merge through a dynamic bridge design. Using yarn made from recycled First Mile plastic, combined with PROFOAMLITE cushioning and rubber surface for power at toe-off, UltraRide carries you to great.
