I'm reluctantly hanging up my VFFs for the winter (again). I just can't seem to shake off niggling problems with one of my Achilles tendons and my ankles have been playing me up in the mornings.

I don't know whether this is down to the VFFs, just old age and trying to come back too quickly after an injury or too much speed work in them (which I love doing).

I shall miss running in them but I can't help feeling that they're a factor in my current problems.
