You haven't really explained what her issue is? Hard to read her mind from here.
How bout some of Dave's (08FJR4ME) rear passenger footboards?
+1 on these footboards. My wife also does not like footpegs and needed a more solid platform for her foot. These footboards were the first farkle I put on and she loves them. They are very well made...all you do is replace the rubber pad on the existing footpeg with these.
