Athletes who spent the past few years embracing or scorning barefoot running can now consider whether increasingly popular “maximalist” shoes — with their chunky, heavily cushioned soles — are the sport’s new wonder product.

Some dismiss the shoes as gimmicky, or just silly-looking. Others, including injury-prone joggers and Olympians, are apostolic converts.

Leo Manzano, an Olympic medalist in the 1,500 meters, runs in the most popular maximalist shoe brand, Hoka One One, which has double the cushioning of standard running shoes. Plagued by plantar fasciitis, an inflammation in his foot, Manzano said the condition disappeared just a week after he tried the shoes last March. In July, he became the fifth fastest American in the 1,500. Manzano is now sponsored by Hoka, which has been accruing a roster of competitive distance runners. “They’re not your normal shoe, but I actually think they’re better than normal,” Manzano, 30, said. “When I first saw them, because they’re so big, I thought they’d be heavy. But they’re incredibly light. My legs felt really fresh after a long run in them. It’s like running on a cloud.”

Hoka One One’s initial customers were ultrarunners, who felt the extra cushioning helped protect their legs from the shock of running up to 200-mile races. But the brand is gaining a following with more recreational athletes. Last year it sold more than 550,000 pairs, which cost $130 to $170 each, and its $48 million in sales were up 350 percent from 2013. Founded in 2009 by French athletes and based in the Bay Area, the company was acquired in 2012 by Deckers Brands, which also owns UGG Australia and Teva.
