Recently I started wear leather soled sandals.
We Japanese call this footwear “Setta”.
Traditional Japanese footwear has a thong “hanao” in the middle, so I think we can train our inner muscles with the center of gravity on the inside.
I think that the whole sole is stimulated and the blood circulation will also improve.
Since the toes open, the sense of balance will be improved and it will also prevent hallux valgus.
We can wear by switching between right and left, so we can prevent one side of the sole from getting worn out.
It’s a wisdom to wear for a long time.
