Lissa made a startling discovery yesterday at Costco. There were no women’s tennis shoes in stock. It was not just that they have become more expensive. There were none available at any price.

This raises an interesting question: have we reached peak women’s tennis shoes? Will women have to start going barefoot? Or will they merely go through the uncomfortable societal dislocations involved with shifting to unconventional shoe options, like wearing men’s tennis shoes?
