As an active runner, hiker and personal trainer who suffers from Plantar Fasciitis, finding the Canna Superior roll-on has been a life saver. This wonderful product (either the cream or roll-on) truly provides immediate, cooling relief. As a plus, what I especially like about the roller applicator is that it doubles as a soothing, rolling massager when my feet are especially achey after a long day. Thank you, Canna Superior.
