Tumbled leather upper. Negative Heel. Rubber and cork outsole. Veg tan leather footbed. Raw Edge seam. Leather laces. True sizing Here we have the Finn II shoes from pic-a-nic pinchers Yogi. OP website lurkers will know this already, but Yogi equips all their shoes with something called a Negative Heel. Essentially, this is a shaping process apparently meant to help improve posture and provide plenty of back support. They dont call em comfort shoes for nothing you know. Other good details include the sumptuous leather uppers, the rubber/cork blend outsoles and the fact they look like a drawing of a UFO from 1897.
