wood

Didn't medieval shoes have soles and didn't they wear out very soon (NL)?

Medieval shoes had merely a thin sole. To prevent this from wearing out too fast, but also in order to prevent the feet from getting wet, people wore wooden shoes called "trip". These are a kind of wooden slippers which could be worn over the shoe. Experiments show that such shoes are worn out after a couple of months. Probably the medieval people then bought a new pair or had the old ones fixed.
