Single-use shoes

Trini's sister is getting married this summer, and as tradition presumably demands, she's dictated the outfits for the lesser members of the party. These are the shoes specified, "Jane" by David's Bridal, which comes in about eleventy-five different colors or can be dyed to match other stuff in the store. It's a pretty innocuous shoe, but Trini objected on humanitarian grounds: it would be cruel, she said, to make her wear heels, even heels this low, for any length of time, and she doesn't care a fig about any presumed advantages of the configuration. I opined that considering these shoes will likely never be worn again unless they're donated to Goodwill or something, it might not be worth the bother or expense. Bridezilla, so far, will not be moved.
