I am checking to see if any other VFF-ers have had foot injuries.
First a little background: I have been wearing my KSOs almost constantly since I got them back in January. I transitioned slowly, building up the mileage. Aside from the usual sore calvs, I had one "injury" to my left foot. During a run, I had some pain on the top of my left foot. When I got back home, it was already starting to swell. It was too painful to run on for about two weeks. Of course, I tried to run on it too soon and had a set back. Eventually, the pain and swelling stopped and I got back to running as usual. Then, in May, I got my Bikilas and transitioned to doing all of my running in them. In June, marathon training started, and I was slowly building up the mileage. About three weeks ago, I was up to 9 miles in the Bikilas with no problems. Actually, I had been running really well and was feeling great. Then, while doing speedwork at a track, I felt a sharp pain in the top of my right foot. It was similar to what I felt in my left foot, but worse. After limping back home, I began a regimen of rest/ice/ibuprofen. I did this for two weeks with no running at all. I also saw my doc (a runner) and had an x-ray that showed no stress fracture. It started to feel better last week and the swelling seemed to have subsided, so I eased back into running. I did two short runs (2 miles each). My foot was sore during each run, but it wasn't bad. There was also some swelling after each run that subsided with ice and ibuprofen. Then, I started out for a third run that week and it all went to hell. I felt a pop in the top of my right foot accompanied by a sharp pain. I limped back to my office and started over with the ice and ibuprofen. I emailed my doc who told me to rest it for two more weeks and see what happens. If it still hurts, he will send me to to a foot/ortho doc.
I think I have a stress fracture to one of the metatarsals in my foot. It hurts pretty much all the time, and the only shoe I can wear to support it without pain is a regular cushioned running shoe (the VFFs flex too much for right now). The conventional advice is to rest the foot for 6 weeks and do cross training (swimming or biking) instead. I know I should have waited longer before running again, so, here I am, resting, riding, and swimming.
I am curious whether any other VFF-ers have experienced something like this and whether anybody has any advice regarding the matter. I honestly do not think it is the shoes. If anything, I did too much too soon, and the muscles in the foot were not quite strong enough which lead to the stress fracture.
If anybody has any thoughts or advice, they would be greatly appreciated.
