Similiarly, trail shoes will have no problem performing on the road. The only issue you may run into is the factor of “softness”.

It's generally accepted that the standard lifespan of road running shoes is somewhere between 300 - 500 miles, or around 500 - 800km, with lightweight shoes somewhere between 250 - 300 miles. So if you're running 20 miles per week, you'll probably need to replace your running shoes after around 4 - 6 months of wear.

Ideally, you want to select a Nike trail running shoe that can stand up to your typical routine. For example, if you cover longer distances (10K+) or have long stretches of road or hard-packed terrain, go for Nike shoes with more cushioning: Nike Pegasus Trail (heel stack: 35.5 mm)

Therefore, running shoes are designed to have thicker soles that act as shock absorbers. They are also lighter than walking shoes to help with fatigue over longer distances. "Because of these differences, ideally running shoes can be used for walking, but you should not run in walking shoes," says Dr. Tenforde.
