The most important thing is to be patient and take your time!
You have to remember that most of the muscles, ligaments and tendons in your feet and lower limbs have been mostly dormant due to wearing shods.
Some people are naturally a forefoot/midfoot striker, so the transition should be easier. If like me, you are or were a heel striker (and used orthotics!), then you have to be a lot more patient. For a heel striker, you are changing completely the way you run so need to give more time for your body to adjust. Yes, you will naturally change to forefoot/midfoot when barefooting (your heel bone would shatter if you continued landing on it barefoot) but your body isn’t used to running that way. You may find that you become a bit excited and try and run a fast 10 mile on road to early, DON’T! That will lead to a stress fracture in your foot (barefoot running wasn’t the cause, it was my own fault for trying to change to quickly and not giving my body time to adjust).
Just be patient and build up the mileage SLOWLY and take more rest days between barefooting (to let your feet and legs repair). Then before you know it, something happens and it becomes “natural” to run this way and you find you can’t wear heavy trainers anymore and you think everyone else who lands of their heels is crazy!

I beat my course 10K (x-country) last week by over 1 minute, so it works for me!

Good luck and enjoy
