Your foot lives in a cave. A small cave. Rather, it lives in a cocoon. Actually, it mostly lives in a sarcophagus, which is like a cave, but with a cocoon for a sock. I’m pretty sure your foot is a mummy.
Try this exercise to strengthen the muscles that spread your mummy toes away from each other. When you spread your toes, you strengthen the ABDuctors of the second through fifth toes as they ABDuct or move in the transverse plane away from the midsagittal plane (mid-line) of your body. But toe spreading ADDucts your great toe because it actually moves towards the mid-line of your body. Confusingly, the ADDucting muscle of the big toe was named ABDuctor Hallucis by early anatomists, at a time when the accepted axial reference line bisected the middle of the foot. Strong toes are essential for optimal gait and balance. Strong toes have great blood flow and a healthy nerve supply.
Place a thick rubber band around all of your toes and spread them. Hold this position for 5 seconds. Repeat 10 times.
The blue muscles in the first illustration ABDuct or spread toes two through five away from your body’s midsagittal plane. In the second illustration, the olive muscle ADDucts your great toe away from the others and towards your mid-line. The pink muscle ABDucts your pinky away from your other toes and your mid-line.
