Chaussure vs. soulier
While both chaussure and soulier can be translated as shoe, they are not always interchangeable. The main difference lies in their frequency of use, context, and the type of shoe they describe. Chaussure is the modern, all-purpose term, whereas soulier is more traditional and specific.
Chaussure
A1This is the most common, modern, and generic word for shoe in French. It encompasses all types of footwear, including sneakers, boots, sandals, heels, and formal shoes. It is the default term you would use in everyday conversation.

Soulier
B2This is an older, more formal, or literary term for shoe. It typically refers to a more elegant or classic type of shoe, often made of leather, like a dress shoe or a brogue. It generally describes footwear that does not go above the ankle. While it can sound dated in everyday French, it is still used in specific contexts, such as in literature, fairy tales, by luxury shoe brands, or more commonly in Quebec French.

Summary
In short, use chaussure as your go-to word for any type of shoe in almost any situation; it's the universal and modern term. Use soulier when you want to sound more formal, literary, or if you are specifically referring to classic dress shoes. Think of chaussure as the general category footwear, and soulier as a specific, more old-fashioned or elegant type of shoe.
