Leather Insole on Tisha Bav

  1. Can one wear leather insoles in a non leather shoe, for tisha b’av and other days that require non leather shoes?
  2. You mentioned that one can’t wear leather insoles in non leather shoes on either tisha b’av, yom Kippur or mourning. Does that include orthopedic insoles from a doctor? because if not one can get back pains from removing those insoles “arches”.
  1. No
  2. In that case you can wear them
