keilainen
Keilainen is a term that can refer to several things, often related to a specific type of footwear or a characteristic of being "keilainen" in Finnish. In its most common usage, it describes a type of shoe, particularly a boot or clog, with a distinctive wooden sole. These wooden soles, often made from birch or alder, provide a sturdy and durable base for the footwear. The upper part of the shoe can vary, ranging from leather to fabric.
Historically, wooden-soled shoes, including those that might be described as keilainen, were practical for agricultural work
Beyond footwear, "keilainen" can also be used descriptively to denote something that is cone-shaped or tapers
