Trailcross LT Mountain Bike Boots Can Do It All be it crossing rivers rocky terrain or sandy surfaces. Five Ten designed this shoe inspired by trail running and we see it in the higher ankle collar mesh upper and slightly curved rubber. Thanks to this design, you can easily move around any terrain without riding a bike. Mesh upper provides breathability and quick drying if you need to get a little wet or get caught in the rain (we've all been there). Strap 'em on and start testing these bad boys on your favorite trails.
