“I thought I would be obvious,” she said. “But with everyone out there, they told me I wasn’t easy to spot at all.”

Are the bright shoes here to stay or destined to be the acid wash jeans of tomorrow? It is hard to say, but shoe companies are selling as much neon as they can, even if some executives, like Patrick O’Malley at Saucony, find the shoes at times “borderline obnoxious.”

O’Malley, senior vice president for global product at Saucony, said he first saw fluorescent shoes in Europe. “We looked at them and said, ‘They’re crazy,’ ” he said. But now, citron is about as common as navy blue, he said.

Newton Running of Boulder, Colo., offered four styles of bright shoes back in 2007. Today, it offers 30, most of which have neon. Brooks, a shoe company based in Seattle, Wash., sold four styles of running shoes last year; this year, it is up to 11. And Nike, the biggest player in the field, sells more than 100 neon shoe styles on its website, at least half of its total lineup this year.
