At least once a day a runner comes in with callous and blood blisters which have formed because of the callous burrowing into the skin. Time and again, I’m told that the person has been instructed not to remove the callous as it is protective in nature. Not true. Although callous initially builds to cushion and protect, eventually it becomes an irritant causing more harm than good.
The above images are of runners whose callouses have become blood blisters. If you have callous, either file it off or seek treatment with a Podiatrist to do it for you. Your feet will thank you.
