Cross over between the trail and the road with the Inov-8 Men"s Terrafly 303 Trail Running Shoe. A combination of a minimal cushioning, a lightweight and breathable upper, and a sticky outsole give you the versatility to move with speed and confidence. Since its first shoe, Inov-8 has been in the business of pushing forward the idea of natural running, and to that end, the Terrafly features a moderate drop for a natural foot position and a DFB shank that replicates your foot"s ability to spring quickly off the toes. This combination of technologies offers smooth transitions during footstrike and quick acceleration off the toes. For the intermediate runner, the 303 is a great racing shoe, and for the experienced runner, the 303 serves as a versatile trainer on dirt or pavement.
