I used this two pairs of boots.  One dark and one light.  It worked really great!  It was a bit messy, which is why I did it outside.  I coated everything really well.  Let them sit out to dry and then when they were dry they were all set to wear.  After they dry they do have a more rough feel to them, but I don't mind.  I used them in rain, snow and large puddles and my feet stayed dry. I am happy with this product.
