In reply to Mark Collins:
The asymmetric bars should sort this. I had the same issue with size Scarpa Cumbre and both DMM Gladiator and Petzl Lynx crampons being offset on the toe section.
With the asymmetric bars I now have a perfect fit with the Lynx. Sadly with my DMMs I'm already using the most curvy bar that fits them so just have to be aware I'm walking on my instep. I find it's not an issue actually climbing but I do notice it a bit when walking.
Before buy some new bars, you can also experiment with the bar you're using as there's two parallel sets of holes which give a few degrees curvature difference depending on which one you use.
In addition, you can also reposition your toe bail (and maybe the heel bail too) such that one side is in the front hole and the other in the rear. If you do that along with making sure you've selected the most curved option on your existing bar you might just get them to fit. If your crampons are new and sharp be careful trying to get the bails out of their holes... the instructions have some suggestions on how to remove them but gardening gloves and making sure you aren't likely to be impaled might be a good idea.
FWIW, the fit you have isn't as bad as I had (I've got small feet and thus asymmetric boots are very curved). I tried moving the bails etc but couldn't get enough from doing that so used the asymmetric bars instead.
