I can say that after a year
I can say that after a year and a half of BFR (now almost two years), my feet did develop a large thickened pad that covered the ball of my foot. And my toes were thicker as well. After being inactive for nearly most of the last three months from having cryosurgery, I am having to recondition that area all over again.
Yes, Seret, I think your feet will eventually get to where you won't notice these changes so much. I have seen both Rick's and Ken Bob's soles, and I can tell you, the plantar skin on their feet is incredibly thick. But think about how often they run barefoot and the distances they run barefoot, the number of marathons and ultras they've run barefoot. I doubt I will ever be able to match them; therefore, I doubt I will ever have soles as conditioned as theirs.
Now if you are talking about my no longer having flat feet and no longer pronating to the degree I once did, then that's another type of foot transformation and another story.
