what do people wear in the gym including footware

i have maybe 5 vest tops got from sports direct £2 each
again have few old tracksuit bottoms
and my superman high tops these are flat and good for lifting had them for a while

so as see my stuff is cheap or old crap

some people like to have the fancy gym clothes lot of people also releasing there own clothes range so so many to choose from

and lets not forget the shoe things with seperate toes

so whats everyones gym wear look like any footwaer like to use
