Obsolet:-after printing this out and trying it on there's a lot of changes that need to be made. I would not download this model unless you wanna use it for kitbashing as a base mesh to build on top of. At the very least the midfoot area is far too tight. Also I think scaling to the one centimetre cube is a bad idea. I've stopped using size cubes newer versions will have registration objects.

My 1st no frils 3d printebel shoes.pre fit test prototipe.UV unwraped.Mat ID's.3 objects in file best printed all in one go.3 diferent objects i recomend a multy matireal printer if posibel ( un tested ).1cm scail object for eazy size chaing to fit you.
