The Netherlands is famous for its wooden shoes. However, nowadays almost no one, except for farmers in the countryside, wear them. You could travel through the Netherlands for weeks and find no one using them for footwear. The only place where you'll find them is in tourist shops. Wearing wooden shoes in public will earn you quite a few strange looks from the locals.
If you do try them on, the famous "wooden shoes" are surprisingly comfortable, and very useful in any rural setting. Think of them as all-terrain footwear; easy to put on for a walk in the garden, field or on a dirt road. If you live in a rural area at home, consider taking a pair of these with you if you can. Avoid the kitschy tourist shops at Schiphol and Amsterdam's Damrak street, and instead look for a regular vendor which can usually be found in towns and villages in rural areas. The northern province of Friesland has a lot of stores selling wooden shoes, often adorned with the bright colors of the Frisian flag.
