Oh, that explains my confusion. Thanks for clarifying.
Sorry for asking this sarahspins - Jackson Marketing hasn't been exactly as helpful as Riedell. Are Jackson heels one step narrower than the ball (e.g., C ball, B heel)? Riedell said that their stock boots have that, but I don't understand how Riedell could be "narrow" if Jackson does the same thing...
You are having trouble understanding what we mean by a last. Everybody has a different basic shape for their boots. In the same way that every different running shoe, boot, dress shoe lasts have a different shape.
Think about a pair of jeans. In GAP jeans, I wear a size 10 bootcut. In Levis, a size 8 bootcut - and they both fit exactly the same way on my butt and legs. However, the GAP pair are more comfortable and fit my waist better, and the cut down through the knee is better for my calves. A Jackson "shape" in a B isn't the same as a Riedell "shape" in a B because they have different ideas on what a "B" should be cut as, and where the curve out should be and how it is shaped etc, same way as a GAP bootcut has a different shaping than a Levis bootcut. Same way that we all have to suffer through trying on different bras to figure out which "C" cup fits our shape best, we all have to figure out which manufacturer and which style fit our "girls" the best by trial and error ...
I also wear a size AAA in one dress shoe, a B in another, and an A in another brand. And I'm a size 5'1/2 in one, and go up to a 7 in another. It all depends on the maker and the style of the shoe.
Forget about the whole "narrow" thing for Riedell. Hunt through the boards for discussions on this. Riedell fits short, fat, long, narrow, different types of feet. It just happens that those short, or fat, or long, or narrow feet happen to fit the Riedell last. Nobody can tell you what boot will fit your feet except a fitter who has your feet and the skates to hand.
