The Fire rings are ok. You don't get to dial in grip vs glide the way you do with a FBV. Which is why some find it kinda meh. Yes, you get more glide than a ROH but you give up some grip in the process, much like you do with a ROH.
I have fixed 4 people I know personally for sizing issues with the TF skates outside of a store environment since they released... not to mention all of the people online.
Would've been a nice thing for True to acknowledge the sizing discrepancies to ensure people are actually in the correct size skate compared to skates they are used too.
