When discussing the rarest of Air Jordans and the devoted few who reach far and wide to grab the most exclusive of gems, names like Simon “depeche23mode” Tan come up almost every time. If you need a thorough reminder as to how deep his collection is, take a look back at our feature on this man’s insane gathering of shoes. If you don’t have the time for all of that, check out this comparison of the shockingly limited UNDFTD x Air Jordan 4 and the even rarer sample version of the shoe courtesy of Simon himself. You’ll notice that the shade of green in the “released” version is a bit grittier and leans toward olive tones, and the rear of the midsole goes a full white opposed to the black panel that’s used in the sample. Seeing the UNDFTD 4s in detail is a rare treat, but side by side with the sample? You don’t want to miss out on this.
