Walmart J's

A pair of Jordan's, (a basketball shoe made by Nike using Micheal Jordan's name, sometimes called J's) that are so beat up, old, fake, and/or obscure that they look like they could have been purchased at Walmart. (Note: to my knowledge, Jordan's aren't actually sold at Walmart)

Person 1: "Did you see Josh's Jordan's, they suck"
Person 2: "Yeah, those are some Walmart J's right there"
