If higher-than-high heels are here to stay, women need more pain-free ways to make it through a full night. Boston-based company Fit In Clouds joined the market less than six months ago, when founder Patrizia Damiani released her own version of foldable flats. Consumers can enjoy the choice of several colors, including black patent (at right), silver, ocean-blue, pink and silver sequined. The flats come in a foldable pouch, which fits easily even in the smallest clutch purse. The shoes are available for $19 to $25 online at Fitinclouds.com and at select boutiques across the country.
