Bone chicks that favor Idalis

from The Notorious B.I.G. (Ft. Angela Winbush & Jay-Z) – I Love The Dough Lyrics on Rap Genius

He is not referring to the shoes. To “favor” someone, is to look like them. Refer to the line from the 50 Cent movie “he favored Rick James” (about the drug dealer his mother fought), but I digress

He refers to sleeping with women who favor (look like) Idalis, most probably referring to Idalis DeLeon, an actress/TV host who is very beautiful.
Basically, he boasts about sleeping with gorgeous women, NOT chicks who like cheap shoes
