This is by far the most effective foot roller for plantar fasciitis pain (and cheapest!). This tool will relieve heel pain in a week or so. 
It can help you to effectively release tight muscles in the deep foot muscles. I even roll out the abductor hallicus, the arch complex and Achilles tendon with it. I still use mine to this day to prevent my plantar Fasciitis from coming back. The little notches really get into your heel/foot super deep. Intense pressure! At first, roll your foot lightly on the foot roller, and slowly over time, build up pressure.
