After a dozen hours of research, we learned that “indoor cycling shoes” aren’t really a thing yet—and that surprised us, since having your own shoes with cleats aligned for your body mechanics can go a long way toward reducing hip and knee injury. So we took a dozen indoor cycling classes and conducted multiple interviews with experts and laypeople alike, and we concluded that the Louis Garneau Multi Air Flex cycling shoes (available in men’s and women’s versions) are the best shoes for most people to use in spin classes. They’re breathable and comfortable, and they’re both efficient on the bike and safe to walk in.
