Skate holders are typically just based off the full size. I would suggest checking on the bottom of your holder to be sure of the number because the width of your skate may change the holder size used. If you use a D width skate the holder number should be 272mm and if you use an EE skate you may have a 280mm holder. If 272, buy size 8. If 280, buy size 9.
