Uniform lattice

Hi,

I'm doing a project and need help mapping a lattice onto a footwear.

I'm able to create a conformal lattice with box morph geometry but what I want is actually a uniformal lattice.

So, I've got 2 questions:

1) How do I get the lattice to not conform to the shoe

2) How do I divide the surface by distance of the uv and not the uv count?

Thanks!
