The Vibram exclusive Ultrafly outsole is made with Vibram Megagrip and has a sticky rubber that works with a chevron lug pattern.
This exclusive outsole also features Vibram Litebase and Traction Lug Technologies. The flat bottom and minimized cross rocker give optimal stability on trail terrain, while the heel-to-toe rocker provides smooth transition. Engineered zones of support in the midfoot help keep you secure.
The fabric wrap on the midsole helps to cushion the foam. The upper is made of vapor weave mesh providing breathability. The shoes have lace up closure and reflective details.
The heel-to-toe drop is 8.5mm and the weight is approx. 300g/10.6oz (Size US 10).
