Nike Gucci Dunk High SB. Only 50 pairs of these made, a collaboration with Gucci for Nike's SB line, were produced as samples. Because the sneaker is on "infinite hiatus" -- meaning it will never be made in mass -- these samples are worth £3000, in order to purchase these you will have to contact Nike.
The red and the dark green really make a nice a combination, with the Gucci logo visible near the heel of the shoe.
