Great for your whole body!
I'm an avid bowler, and I ache from the feet up to the shoulders...  Reflexology helps smooth the pain, but its expensive...  The Hi-Dow Massage shoes comes in at a great price, and I can use it for as long as I like with out the cost of hundred's of dollars.  It uses EMS shock and can be controlled or just strap on the shoes and walk around for bit helps too.  I give this product an excellent rating.
