Reply To: Crocs on Tisha Ba’av

BTW this question was not always so obvious. It’s brought diwn in the Sefer Minhagim that the Maharil was mechadeish davar when he allowed people to wear a new garment called “zocken” on their feet on Yom Kippur rather than go completely barefoot. Seems once upon a time, the idea was to be uncomfortable and not merely avoid leather.
