I am the partner in question
I currently use Petzl Vasak crampons, and before that I was using Petzl Sarkens. They both fit fine, although I had to take a hack saw to the bars to stop them sticking out the back.
As Sea said, I have also successfully had Cyborgs on my boots, although I couldn't tell you how they were set up.
My feet measure at 2.5 and my winter boots are around European 36 or maybe 37 (3-4ish). The are La Sportival Nepal Evo Gtx, the green ladies version if that is any help.
