With the outsole lugs (4mm) and base rubber (1mm), the full-stack height is 30mm at the heel and 24mm at the forefoot. This is Inov-8’s deepest-ever foam cushioning. While there’s no rigid carbon plate, this is still a long way from minimalist footwear. The Trailfly Ultra G 300 Max features a 10mm deep groove under the arch of the foot
For trail running I uses Altra Lone Peak 5.0, Altra Olympus 4.0, Saucony Perigrin 10 and Inov-8 Trailfly Ultra G 300 Max. Only the Lone Peaks has any ground feeling and they are the shoes I enjoy the most running in. ect0.
