A nimble and low profile design with a touch of protection from the road, the Inov-8 Road-X Lite 145 features minimal cushioning and a firm ride.



The Inov-8 Road-X 145 is a lightweight, natural running shoe that offers the utmost in proprioception for the minimalist or elite runner. Unlike other Inov-8 models, the Road-X 155 doesn’t incorporate Dynamic Fascia Band but rather relies solely on foot strength from the runner. The Road-X 155 offers a 4mm heel-to-toe height difference that allows the runner to run in a smooth natural running style.
