Sneaker

My friend told me that he is importing sneakers to be used for line dancing. It is a special shoe that can bend backwards, and is good for dancing.

What is a sneaker? I found the definition from Wikipedia:

An athletic shoe is a generic name for a shoe designed for sporting and physical activities, and is different in style and build than a dress shoe.

Originally known as sporting apparel, today they are known as casual footwear. Athletic shoes, depending on the location and the actual type of footwear, can also go by the name trainers (British English), sandshoes (Australian English) running shoes or runners (Canadian English, Australian English, Hiberno-English), sneakers (North American English, Australian English), sport shoes, gym shoes, tennis shoes, tennies, sneaks, takkies (South African English).
