I have to admit have been the best nursing shoe I have ever worn. I suffered from heel pain 3 years into my nursing career and tried every shoe out there. I finally found Z-Coils and can honestly say made working 12 hour shifts feel like 8 hours. The company is based out of Albuquerque www.zcoil.com
. You have to go in and get them custom fit at a Z-coil store. As far as cost they are not as expensive as the amount of money I spent on shoes every 3 to 4 months. The great thing about them is that the coils are all replaceable so you do not have to buy a new shoe every 3 months. I actually purchased my first pair of Z-Coils from the founder of the company back in 1998 in Albuquerque. Good luck!!
