Copped both pairs, was glad that I went half size up since I found the SP/TB fits half size snug than regular core black 3.0. The official name for these is UltraBOOST LTD Luxury Pack BTW. For some reasons the grey one really reminds me the Hisnobiety Collab... maybe because of the real leather tag? Top of the lace is made out of metal, a very nice touch. Leather insole doesn't give as much grip as regular ones and feels slippery but gives premium feel. The knit on the black ones is different than the CB/TB, the wave pattern shines when look at certain angels. Overall for retail of $200 defenitely a must cop.
