I've changed from my beloved Asics 1090 recently to Asics 1110, on advice of running shop (and there's no chance of finding the 1090s any more!) and my left achilles tendon is aching like mad.
I've had a week's rest, thinking it was just very tight after recent v.long run, did the icing/elevating routine and it was better until I put my shoes on yesterday to do a short run. I think it could just be that the shoe is rubbing against the tendon.
So, is it ok to carry on with a grimace on my face, or do I need to take it more seriously?
