for me, the worst one i've worn and seen are the CDP XI (i'm sure this has been said by people already)
shoes "look" good, but once you have them in your hand, you can instantly tell that the shoe will be uncomfortable.
there is barely any padding, and one soles have no cushion at all. not...
^Agreed, especially Nike Clearance stores, which have shoes usually cheaper than the standard Nike Factory outlet stores.
Sometimes they carry B-Grade Nikes/Jordans that are very popular.
A few examples I've seen myself: Cough Drop Foams / Anniversary XIs / Penny 1/2 Cents / ect.
