Super shoes have taken over elite road and tracking running in the decade since they first emerged with Nike’s invention of the Vaporfly 4%. One category of runner that hasn’t gotten the same boost that everyone else got when super shoes appeared: trail runners. Research on trail running can be hard to do. Simulating rock and switchbacks on a treadmill in a laboratory poses some readily apparent challenges. Two recent studies provide some answers though.

Running-related overuse injuries remain a plague on the sport, sidelining some 20% of runners for at least a few days each training block. Shoe manufacturers and running retailers have worked with clinicians (podiatrists, physical therapists, etc.) to help runners and walkers alike find a footwear solution that will keep them free from injury. With the advances in shoe design and materials science over the last decade, what should we know about footwear's injury-reducing c
