Any cobbler worth his bootblack can polish wingtips or resole a pair of Winklepickers, but when your shoes need something extra, try John Ngo at Ventura's. He'll make custom insoles and build up (or shave away) outer soles to correct pronation, supination or just plain irritation. We took a large friend with severe ambulation problems here and Ngo crafted a pair of corrective soles for a pair of leather shoes that made all the difference. He'll also repair cowboy boots, purses and belts. English isn't Ngo's first language, so be patient. But he'll make those Dr. Martens last a lifetime.
