When I had my gait analysis done a few weeks ago, I got to try out all the trainers they recommended on the treadmill before I chose a pair. I went straight out that evening and ran 5km in the ones I chose, no problem at all and no breaking in required. Previously I was running in some cheaply ones from Sports Direct. My new ones are new balance – I am also a neutral runner.
Could you go back to a different gait analysis place and test some out before you buy?
You could also try some insoles. I’ve just ordered some Footreviver insoles for my hiking boots which give me blisters on the balls of my toes. They are supposed to be suitable for running too.
