If you're going to spray a protective material on your coveted sneakers to keep them from getting messed up, it's probably a good idea to read the directions first. The man in the above video learned that lesson the hard way after applying Crep Protect—the popular product that's often advertised by having people pour ketchup and chocolate on their shoes—to his leather Jordan 1s only to see a white film appear after.
What went wrong? According to a rep at Crep Protect, the recommended materials suitable for the spray are suede, canvas, and nubuck, so people shouldn't be using the stuff for leather sneakers anyway.
The rep speculates that the recent "Banned" Air Jordan 1's leather is treated with a chemical in the production process that reacted to something in Crep Protect's compound. Crep Protect maintains that the majority of leathers won't have this sort of reaction to its product (Reinforcing this is the guy spraying his "Shattered Backboard" Jordan 1s with the stuff in the video without any negative side effect).
Crep Protect says it's reached out to the man behind the YouTube video in an attempt to rectify the situation.
