The Fossil Canyon, from Teva, is a great mens sandal from dawn to dusk, both rugged for the river & stylish enough for the streets. The Fossil is a premium quality trekking sandal & boasts a blended polyurethane/EVA unit in the heel cup that evenly transfers the energy of impact throughout the footbed & away from the heel. This energy return actually provides greater spring with each forefoot push-off.
