Three-time NBA all star (and these kicks' namesake) Gilbert Arenas is apparently quite a Halo fan-he even sponsors a team of pros known as Team Final Boss. These kicks were launched to promote the release of Halo 3back in 2007, and they were made in a limited run of only 100 pairs. At least they didn't try to do any in-game tie-ins-can you imagine Sgt. Johnson sporting a pair of these?
