eli5: Why are flat feet generally worse than arched feet, when you have more surface area making contact with the ground?
In: 191
While I can’t give you a good answer, I can give you one based on lived experience with a knee that basically fell apart in a skateboarding accident.
If I’m standing in place, I now stand on the blade of my right foot because it relieves weight from the medial side of my knee preventing it from feeling like it’s buckling. If I roll my foot to the other side, suddenly the pressure is immense in that spot.
The arch of the foot alleviates weight on the knee joint by acting like a cushion and directly the leg upwards to the hip correctly. If your foot was flat the cushion wouldn’t exist and there would be more weight placed on your knees.
