The gemara talks about how since spiked shoes (cleats?) were involved with an incident where many Jews were killed, we don't wear them on Shabbos or Yom Tov. Since they have no use, the mishna says that we can't give them as gifts on Yom Tov.
My question is, if they were banned on Shabbos and Yom Tov just because of the fact that the incident (Basically, lots of Jews were hiding in a cave from some oppressors, and they were found, and in the ensuing panic, many were killed from these shoes...this happened on a Shabbos) happened on Shabbos, shouldn't we ban it for during the week also? Had the story happened during the week, wouldn't they have also been killed? So why was the ban only on Shabbos and yom tov?
I asked this to a guy in shul, and he gave me the following answer. Because it happened on a Shabbos and they were hiding, they didn't have any light inside the cave to be able to see anything. Had it happened during the week, they probably would have lights of some sort and they could have avoided killing people accidentally.
Also, what were these spiked shoes? If they were cleats, with spikes on the bottom of the shoes, how could they wear them on Shabbos in the first place? They would be making holes in the ground (plowing)!
