what kinda heel do you have? what skates did you wear before? I'd say I have a narrow or narrower then average heel. I was wearing Graf 703's for the past five or so years. It's so hard to tell what will work for you without trying them on. Also look at CCM Vector's. They have a narrow heel and mid foot. what prompted the change from graf to rbk? Comfort. I was never really comfortable in my 703's. I had nasty lace bite, my toes always hurt after skating and me toes froze in them. Come to find out, the 703 wasn't wide enough for me and the toe box was too small. This was largely my fault though. I needed a skate with a wider forefoot. Something a little deeper too. I assumed you had sacrifice comfort for performance and dealt with it. Crazy huh. There was a huge sale at my LHS back in Aug so I thought I would look at some skates and see if I could find something a bit more comfortable. The 8k's fit great and were only $250 US. I was and still am impressed with the performance of the skate. No more lace bite, no more sore feet, and no more ice cold toes.
