Isn’t there a difference in how crocs are used (in the sense of causal-wear vs. daily-wear) between Eretz Yisroel and America that would affect the applicability of the psak?
I don’t understand the question. I wear my Crocs every day, even to work, where we have a dress code. I also wear them around my apartment. Am I wearing them for casual- or daily-wear?
(I assume you mean “casual” and not “causal.”)
