I have plantar fasciitis. I also work 14 hour days and have a 1 year old and a 3 year old, so staying off of my feet is not an option. I have spent untold amounts of money on my feet, including custom orthotics, injections, and so many other gimmicks I can't name them. I am considering shelling out the bucks for some MORE new shoes and I was thinking about MBT or Z Coil. I would like some input from anyone/everyone. Thanks!
