Barefoot running CAN reduce impact force.
But...
You can work hard and aim for best results, but…….
It can also increase the impact force, beyond that which occurs when wearing shoes
Shoes reduce impact transient, absorbing impact at the heel
Shoes do a pretty good job of "dampening" the loading rate

Theoretically, BF running can reduce impact force & loading rate
But this depends on CORRECTLY running barefoot
The impact transient is absent when barefoot
It is possible to change the forces using conscious technique training
The majority of shoe-wearers are heel-strikers
Shoe-wearers still heelstrike when barefoot.
At least at first
Habitually barefoot runners overwhelmingly forefoot strike
People who habitually run barefoot are more likely to forefoot (or midfoot) strike
