Dont´t bother, they are the worst bit about these crampons. I have destroyed mine in one day of mixed glacier /moraine travel, while the Grivel plates of my partners looked like new. I have since fit antibot plates for old Grivel G14s on my Aiguilles (no idea whether the new ones are different in size). The front plates fit as is, while the rear ones will need to be cut down a little bit (the Airtech rear plates should fit perfectly, but then the front ones would be too short). The Grivel plates are just so much better, both in terms of robustness and in expelling snow.
