When I was in college, a friend often wore Birkenstocks, the backless shoes that are the tree-hugging cousin of the flip-flop. The shoes reminded me of crunchy granola and the Hare Krishna food they used to give away on campus at the University of Florida. This was back in the nineties before Nordstrom carried the comfort shoe in an array of pastels. I was poor in college, so a splurge for me was a 2 a.m. run to the border for a nacho bell-grande. In hindsight, I should have opted for the free food passed out by the bald people wearing white sheets and dancing with tambourines. It was probably healthier. But I was afraid if I ate the Hare Krishna food I would end up in a hallucinogenic state and disavow my beachy flip-flops for its chunkier cousin.
