IMy family had the largest fine shoe store here from WW 1 until the early 1980's. I have seen everything possible being done to shoes.
With leather, I would suggest having a shoe stretcher around. You never know when a shoe is going to rub your foot or whatever.
Bunions that aren't inherited come from shoes that grip the foot on the sides, like ballet flats, and high heels. Other bunions come from shoes too tight.
I know I have to really stretch my Fly London for several weeks so the leather doesn't draw up on me.
After you leave it in the position of stretch you want for several days, it will snug up a little because leather/and skin are somewhat elastic.
