Having just one pair of shoes for road running, trail running and workouts is tempting; however, we recommend using the appropriate shoes for all occasions. The best trail running shoes will protect your feet on uneven terrain, while the best workout shoes will provide grip and stability in the gym.
Especially if you do heavy lifts in the gym, a cushioned, high-stack running shoe might not be stable enough to provide you with the sturdy platform you need when dangling heavy weights above your head. Similarly, no matter how responsive the best cross-training shoes are, they won't be able to pick a fight with dedicated running shoes on the road.
