Fabricgator, I purchased the Z-coil tennis shoe like 4 or 5 years ago and at that time they were pricey to me, but such a good walking shoe at $81.00, I have never regretted that purchase. They are amazingly comfortable to walk in with the spring on the heel. I was shocked to go to the web site now and find that, that price now is up to $259.00!! Out of curiosity you could still go to
http://z-coil.com and checked them out, but that price sure blew me away! Super comfortable shoes and I still wear them when I have to go somewhere and walk all day.
