Shoe wear tells our walking/running gait pattern story.
Wear above the big toe is not uncommon as many of us in the west struggle with ankle dorsiflexion because we no longer squat throughout our day.
Squatting deeply is one of THE best movements for the lower body. If you struggle you can use heel lifts of even a chair to begin.
Without the ankle mobility our toes (particularly big toe as it’s 4 times stronger than all the others) will try to help out by lifting up.
But without eccentric control of the ankle, the foot will slap the floor, over time causing pain in the toes or big toe.
In this case my clients pain in his toe was resolved within a week of consistant awareness and exercises.
