The Inov-8 Road-X 155 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.

INTRODUCTION

The Road-X 155 is a minimum feature, minimum neutral shoe intended for speedwork and racing.

CUSHIONING

  • 1 Arrow Shoc-Zone provides minimal underfoot cushioning and a 3mm heel-to-toe drop. This is Inov8's 2nd lowest level of cushioning on their 0-4 arrow scale. 

MIDSOLE

  • Injected EVA Foam for resilient cushioning with maximum memory retention.
  • Dynamic Fascia Band running from the heel to the forefoot acts as a rigid lever arm, releasing energy with each step and propelling the runner forward.

UPPER

  • Synthetic Mesh covers the upper for lightweight, breathable coverage.
  • TPU Lacing System uses TPU lacing supports for a strong, lightweight and secure fit.
  • Met-Cradle is a synthetic webbing upper that supports the forefoot and provide a secure fit.
  • 6mm Footbed for additional underfoot comfort.

OUTSOLE

  • Road-X Lite is a lightweight outsole intended for road racing, speedwork, and everyday training.
  • Fusion Compound is a mix of synthetic rubber and EVA foam for a smooth ride and grip on the road.
  • Meta-Flex groove is located at the forefoot to encourage natural forefoot flex during toe-off.

LAST

  • Anatomic Last follows the natural shape of the human foot for a close and comfortable fit.
