Will these fit my Diadora road cycling shoes.Is it one size fits all ?
As long as the heel pads on your particular pair of shoes if replaceable then yes these Sidi Rubber heel pads should work.
No, these will not fit you Diadora's. Only some Diadora's have removable heel pads and those that do are screwed on from the sole side of the shoe. You will need to find a Diadora replacement.
