Customizable Footwear 3D Model

I need a clean, production-ready 3D model of a single footwear item built in Blender. The mesh should be properly scaled, neatly UV-unwrapped and organised in clearly named collections so I can swap assets fast.

Key requirement: every surface must accept interchangeable material textures, colour variations and pattern overlays. Think of being able to drop in a new leather grain, switch the sole to rubber in one click, or audition fresh prints on the upper without touching the geometry. To make that smooth, please set up well-labelled material slots and node groups that expose texture, colour and pattern inputs directly in the Shader Editor.

Deliverables
• Native .blend file with non-destructive modifiers applied only up to subdivision preview level
• All textures packed or placed in a separate folder and correctly linked
• A brief note explaining where to adjust materials, colours and patterns

Once delivered, I will test by changing textures and colours myself; the model is approved when those edits update flawlessly in the viewport and render.
