There is a lot of Possibilities to turn your Sneakers into a unique Piece of Art.
The following can be implemented by me.
When properly prepared, pretty much every material can be painted or dyed - From high-contrast Colorblocking to filigrane Patterns everything is possible.
Exchanging certain Pieces and professionally re-constructing them onto the Shoe leads to precious Results - not only do I have access to many high-quality Materials, I can also use most of your own Materials.
Depending on their Upper Material a lot of modern Sneakers can be stitched upon.
If you want to build up your very own Sneaker from Scratch, go for a "Bespoke" - Sewn from chosen materials, based on the existing Sewing Pattern.
