I used to always wear a size 9 skate, and then went to Xsjados, and since then, I haven't really fit into a 9. I was skating a pair of the 10 RB's, and liked them, but I've always liked the smaller shells a lot more. So, I bought a pair of 9 skates for $50, and went to hacking. Did a little more work with a dremel tool, and shaped the cut more to my liking. Still need to do a little bit of work to them, as the area where my toe makes contact with the end of the shell is too high, and needs to be cut down for comfort. I liked all the modifications I did though. The skates felt a lot better than the 10's and the cuffs had a lot more flex.
Gaas, I'm not sure what you mean. Like, is the cuff too high on the skate? Cause that can be cut down (I recommend it). I don't know what the liners you are talking about look like though, so it could work, and could not.
