Sorry, but I'm a little confused about the fit profiles.  I "thought" the older Reebok 20K, 18K, & etc had a larger fit profile (wider forefoot, toe box & etc)?  Then when the Ribcore line came out, it was a narrower fit profile, with the RBZ taking the larger fit profile roll in the CCM/Reebok lineup ( with Tacks sitting somewhere in the middle).   So, are they (CCM) now saying the Tacks/RBZ line is equivalent in the terms of fit profile, to the older Reebok 20K, 18K, & etc?   Thanks!
