Due to the rare size and color, the price has skyrocketed. Counterfeit goods are circulating, but there are virtually no 30cm US12 size fakes. This price is set because I can guarantee they are authentic. Nike Air Jordan 1 Retro High OG Lost & Found / Chicago Purchased through SNKRS exclusive access, guaranteed authentic. Size: 30.0cm / US 12.0 This size should fit someone who usually wears 29cm. Wear your AJ1s big to make a statement! Wear them or display them! This is a very valuable pair.
