Because the stress points of human feet are at the big toe, the heel and the distal end of the fifth cover (that is, the joint between the foot and the smallest toe).
These are just three focal points, and stability comes from these three points. As long as these three points are not destroyed, then walking should be stable. There is no obstacle to wearing socks.
But I was a little unaccustomed when I was just cut off. I will get used to it after practice.
I hope I can help you.
