My skechers sneaker soles are too slippery. How can I fix them to have more traction?

I do not know if its just Skechers or other brands as well but these cheap crappy sneakers (but hey they look good…) from Skechers and Costco have the worst soles.  They are almost flat with no traction and in the rain they are incredibly dangerous.

Is there some simple and hopefully reasonably cheap or home made fix to creating more traction on the soles so I do not kill myself walking in the rain?
