Bought these for hiking/running trails. They are my second pair. They fit well and have sufficient grip in the terrain. If you only ride on paved roads, the treads wear out quickly, just like any other trail running shoe. If I run strictly off-road, I run in Saucony Peregrine shoes. For a mixture (off-road and asphalt) I use the TR15. Good shoes, good quality. Not the best of Saucony deals for exclusive trail running, but a good bargain.
