Forum:Knuckles wears socks-??

i heard someone say Knuckles wears socks that are the green you see above his shoes but they look like solid sharply-edged cylinders which i always considered to "go" w/ those metal slates of "armor" on his shoes. im fine w/ them being socks (not as cool, but he can make anything cool!) but i dont like thinking i know when i dont. what ARE they ? do they ever say-for a fact-that theyer socks? (i cant imagine a professional interviewer actually asking "hey, what are Knuckles' green socks?" said person would have to be a real fan ^-^ )
