It's the base of the 5th metatarsal. I was driving after one day, only wearing the shoe half of the time after a week and by the end of the second week the shoe was gone and I was using the cross trainer, after 3 weeks I was going to spin class twice a week and after 6 weeks I was discharged from Fracture Clinic. After another week I was running and built this up over the next 3 weeks but pain returned and I went back for another x-ray. All of the above was with fracture clinic/Physios agreement and seemed to be going OK.
