I did it!!!!!! My very first run!! I am doing to couch to 5k, plan......and just got back. Just about managed it, am very very unfit so am pleased! I too went to a proper running shop, and spent nearly an hour in there, having my gait, in step, (little run, which was recorded on a treadmill - to see how I landed etc) I spent £65 on a pair, but do have back and hip problems, so really didnt want to do more harm than good!
Will let you know tomorrow, if I can still actually walk! Rest day tomorrow, so next run is wednesday!
