John Geiger and The Shoe Surgeon just pulled back the curtains on their latest custom sneaker project, and this one's worth the wait.

This time around, the duo stick with Geiger's staple Nike Air Force 1 to create a handmade low top that features heat sensitive, color changing purple leather uppers. Sounds crazy, right? Instead of trying to do it justice with words, we'll let the clip above do the talking.

Aside from the color changing leather treatment, these custom Air Force 1s appear to use a deconstructed build with minimal padding around the ankle area—perfect for stunting in the sun.

There's no word if this pair will actually be released to the public, but we do know that Geiger will be doing a special release for a to-be-announced sneaker at tomorrow's Baltimore Sneaker Show event, so don't miss out on that if you're in the area.
