PUMPED UP KICKS

 (slang) Shoes, specially sneakers. The very expensive and stylish kind.

Here's the original PUMPED UP KICKS:

( NOTE: check the round orange basketball like PUMP logo on the 'tongue' of the sneaker. As you squeeze it the sneaker fills out with air and feels more comfortable )

*The original Reebok Pump was released in 1989, as a basketball high-top shoe. The shoe was quite expensive compared to other retail athletic shoes at the time, often costing as much as 150% more than the next most expensive athletic shoe on the market. It became something of a status symbol on urban basketball courts and eventually in suburban high schools.

Nowadays the cost is still  too much and most people don't wear it anymore so when you hear PUMPED UP KICKS people refer to expensive sneakers in general.
