Natural wrinkles on feet G8

Camthaleon

Is there any way to have natural wrinkles on the the soles of feet for G8? I've looked around the forum and one answer proposed a complicated way to incorporate wrinkles into the texture. Since I don't know Photoshop and/or Blender, this is impossible for me. 

I tried playing with Bump and Displacement map but bump map doesn't do a lot and displacement maps displace the skin often resulting in weird shapes.

I think displacement maps would be the way to go, but it would be kind of difficult to do correctly, which you've already discovered.

The other option would be some type of HD morph which I think only the PAs have access to.
