I have a CCM Skate sizing vs. Bauer skate Sizing question.   CCM 50k Ribcor size 9.5D for example has a 287 size holder while a Bauer MX3 9.5D has a 280 size holder.  Why both same size skates but different size holders?  Are they actually the same size or is there a half size difference between the two?  Thank you in advance
