Even in retirement, Ray Allen's player exclusive sneakers are in a class of their own.

With his autobiography From the Outside recently making the New York Times Best Sellers list—it's currently ranked No. 7 in the sports and fitness category—Allen took to Instagram to celebrate the moment by showing off a few never-before-seen PEs.

Pictured alongside 2013's "Two Rings" Air Jordan 11 are Celtics-themed Jordan 4s, Jordan 11s, and Jordan 14s, each of which use white-based uppers with green and gold accents to match the team's alternate jerseys.

While the chances of these pairs hitting retail are slim, an Air Jordan 28 inspired by Allen's performance in Game 6 of the 2013 NBA Finals will release on May 12 as part of Nike's "Art of a Champion" collection.
