So what is footsies

I here the term talked about all the time, but somehow it seems that it hasn’t had a proper introduction here on the newbie forums. So what are footsies all about?

All I’ve gathered from watching tournaments and such is that it is using normals to maneuver and get close to an opponent/keep an opponent away. Is this correct?

I keep hearing that I need to work on footsies, but that’s difficult when I’m not sure what it is… Help?

Prepare to be enlightened.

thank you thank you thank you
