I was having pain when I am doing inversion motion on my feet, the rock tape sort of restrict that direction of movement, applied by one of my friend who is a doctor. Kinesio tape works the same but she says it comes out when you swim and they cost almost the same. She say their clinic abandoned kinesio tape altogether and opt for Rock Tape instead.
It has other usage as well, tape your blister prone area. Although it's going to be pricey. hmm promotion too much of a product.. I am usually quite sceptical about products I am about to use
