Buying new clothing during the Nine Days leading up to Tisha b'Av

Hi,

One may buy appropriate footwear (ie non-leather shoes) for Tishah b'Av during the "Nine Days" period of mourning leading up to Tishah b'Av, if one was not able to purchase it beforehand.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 3:80)

Have a great day,
Mordechai
