Petzl M10 compatility

[mzamp]

I have a pair of Petzl M10 crampons with a wire toe bail. These worked great on my La Sportiva Nepal boots. However, the boots gave me blister so I just bought a pair of Koflach plastic boots. At first attempt at fitting the crampons, the toe bail doesn't fit into the toe welt.

 

I would think these crampons would fit better on the plastics. Do I need a different toe bail?

Petzl crampons typically have small, narrow bails that fit well on single boots, but not so well on large plastics. Pick up a BD or Grivel bail; that should solve your problem.
