high poly uvs

That is done by Baking the Normals from the High Poly onto an Image Texture and using that (with the UV Map of the Low Poly) to 'fake' those indents.

There are many tutorials explaining the process in detail, just look up Normal Map Baking in Blender, or so.

(This is a too complicated process, to explain here, sorry.)

Hey mmuqaddas ,
There are lessons within some courses that will guide you through the baking process...
Here is one, Baking the Normals Lesson - Animated Sci-Fi Game Environment Creation Course

As for where to place the seams, it's a good idea to place the seams where you see them on a real shoe. Take a look at the seams on your reference.
You don't need to mark seams and unwrap the high poly, only the low poly, so when doing the retopology to create the low poly shoe keep this in mind.

The Game Asset Creation Playlist will guide you through different scenarios and projects to learn the complete process.

Also it looks like you can achieve that with texture painting as well, it's just a bunch of duplicated circles. So if the normal map gives you too much of a headache, I think you can totally paint that detail in, it will require some patience though. 

Rate your normal? Probably a language barrier? 

Hi mmuqaddas ,

I'd say your Normals are wrong ('flipped')...the indents look like 'bubbles' (raised from the surface).

Look at where the light is coming from and where the shadows are:

Yes I agree, there is a mistake in that. Also is putting the texture node to none-color data still a thing? Perhaps you also have to set that up.
