The Gemora returns to discuss various customs which one must not permit in public including wearing a wide kurdekison sandal outside on Shabbos, and we are not concerned that it will slip off and he will pick it up. Nevertheless Yehuda and Hillel, Rabban Gamliel’s sons, wore them in Birai, and were slandered, saying that they never saw anybody do that. They slipped them off and gave them to their servants, since they didn’t want to tell them it was permitted. This leads us to the discussion of the Greek etymology of the kurdekison a dancing shoe and the dance known as the Cordax (not the Lorax!).
