Nike Air Shoe Inserts Shoe Trees Cardboard size 10 to 10.5 NIKE authentic. Shipped with USPS Priority Mail. Hello, you are viewing three sets of Nike shoe trees cardboard inserts that come in nike Air jordan or forces that are sold in stores. These are sizes 9 to 9.5. Basically, I think they would fit from an 8.5 to 10 just fine. These are authentic Jays and came out of random Jordan shoes, and each is a left and a right and came from the same pair of shoes. It's not a random left or right. These are the ones that came in the actual shoes in the box. Please feel free to ask questions, and please review my other listings. All of my merchandise is 100% authentic and will be packaged precisely. Thank you! These are getting harder to come by . Please feel free to ask questions. I do have other sizes as well. Thanks!  Update Nike is no longer using cardboard shoe trees and us only using paper, so these are even rarer now. The rubber bands are to keep them together. There may be small imperfections on the product, but they will serve their purpose and have no tears or anything like that, just little marks that are just from the factory. These came straight out of the shoes and into a box. LAST SET OF THIS SIZE!!!
