How do I track this shot in mocha pro?

I understand that Mocha struggles with Shadows so how do I solve this sense a majority of the surface is covered in a shadow?

Expand the mesh beyond the actual tracking area around the whole foot. You have enough info there with the edges of the foot, the toe nails, the spaces between the toes, the veins and so on. You can always shrink the actual tracking area later.

So draw the  mesh shape layer outside the foot a little?
