There is actually no premium. It's retail. The only difference is that we include worldwide shipping, which is actually cheaper for anyone not located in Canada. Our derby will probably use a Dainite sole which, IIRC, is not planned for the Viberg site.
But they are supposed to be wide. Wide can create a draped effect that is impossible with narrow. I think that there is room for both, even in the same collection. For example, I have some pants from Cloak fw04 that have a 20"+ hem. The sister jeans from the same collection have a 13.5" hem. Both look very cool.
