I've dabbled with sculpting and texturing the shoe in Mudbox. I have put it together roughly in order to practice with setting up displacement maps with shaders in Maya. It can be quite tricky.
It is far from perfect, but I should be fairly pleased that I have got a result at all.
So this has the sculpt in the shoe on the outside.
And, if you have a look at some of the textures, for example, the laces and seam on the side of the shoe, you can see that they need some time put into them. This is due to just testing everything out before I go into high details.
Here you can see some the issues with the displacement map in this ambient occlusion layer - especially at the toes...
The texturing process in Mudbox is quite efficient, especially that you can export them then open them into Photoshop if you wish to tweak them before going into Maya with it.
See, a comp' can make anything look better. Even a rough Photoshop one (yes, specifically by blurring poor textures!)...
