narrow heel wide toe box NNN skating boots?

i am looking for narrow heel wide toe box NNN skating boots? i have
been looking a little and found that hartjes boots are made this way
however they are not NNN binding compatible.
i currently use atomic boots NNN but the toe box is almost too small
and the heel is not quite snug enough
even with different footbed inserts (i use green superfeet).
i do not want to change all my bindings! i do race however i only race
for fun ( western sierra's) so i am mainly interested in comfort .
thank you.
