What are z coils?

Answer:
They refer to a type of shoe that has a coil in the heel that is suppose to reduce heel pain while walking

Z-Coils are excellent for heel pain or any kind of foot pain. They also are great for people with back pain or knee problems. They are fabulous for walking for exercise and for people who are on their feet all day. The heel is actually a coil, so they look a little like high heels, and they look terrible, but when your feet hurt, you don't really care what they look like.
