Made to fit any standard croc shoe. Free Compass included
 
There are 2 spowerful 3x10mm Neodymium magnets on each jibbitz so these can be use with either the North or South pole. Most people like to use the North Pole since it is stimulating, whereas the South pole is relaxing. So it depends on what you wear your shoes for. 
 
Caution: These magnets are powerful and have a field that extends around an inch so the field can penetrate deep into your body
 
There are 13 top holes and 7 side holes so 20 total possible holes to fill per shoe. 40 if both shoes holes are filled. 
 
In acupuncture the feet are connected to everywhere else in the body and the pineal gland corresponds with the outside of your big toe. Most people these days have a callus there so that would be a great spot to place a few of the magnets. Perhaps one on the side hole and two up top. Of course there are many other beneficial points, especially around all the toes .
 
Enter in the number of how many top or side ( ex all 6 top, or half/half, or 5 top and 1 side). If nothing is specified 50/50 will be given
