Keep in mind I have yet to try a pair of Carbons on and i'm still interested in trying them... But:
I have a pair of K2 Radical 90's in size 8.5 that I've used for a few years... When I think of this type of skate being adapted for grinds and such... There is just something that seems like it wouldn't feel right for park/street skating. My ankles start to bleed just thinking about it. Obviously the construction is different between a radical 90 and a carbon. But the general feel of the skates would be similar.
Originally I thought they might skate like the OG remedyz. However, the more I think about how different my OG's feel than my racing skates... The Carbon hype in my brain begins to fade... I think these skates aren't going to hold a candle to the OG remedyz. But they could be fun to try out.
A lot of the excited reactions/hype comes from people saying they are light and compact. Many of these people haven't tried racing boots before so obviously they will be excited by a different feeling boot... In the end a light, compact boot doesn't matter as much as the feeling of the skate(for me at least). The Carbons might just feel weird... But again... I'm interested in trying some to put the rest of the hype out in my brain.
