Coach JP always runs with Altra shoes. They have an extra-wide toe box and an ideal foot pattern for rocky trails. He uses them for road races as well, and even for workouts in the gym. Altra features three different trail running models with varying degrees of cushioning and support. Coach JP prefers the Olympus (which has the most cushioning making it his choice for the rockiest of runs) and the Timp (which while it still has cushioning, has a greater feel for the ground).
Men’s and Women’s are available on Amazon in a variety of sizes and colors.
