Yeah get the Imperials. I'm also thinking of imperials. They fit good width wise?
32's are the only boot I've word that works with my width, but then there is too much volume elsewhere (skinny ankles, heel and low volume foot)
Can't comment on width for you, but they seemed good to me. Does Burton make 32s? Cuz they seemed very similar in liner and construction. The lashed I tried were even softer than the Ambush, or so it seemed.
Think I'll at least call my local and have them bring in some Imperials in my size.
