Since the front points are so long, a large lateral force on the very tip of the point will produce a large bending moment at the base of the point. If you look at the base of the point you will notice that this is where one of the front adjustment holes is located. In other words, they have drilled out metal right at a place where it is badly needed for strength. The first time I bent one of mine I removed the shoe and pushed the point against a rock to straighten it. It immediately broke off. Sherpa replaced this one for me under warranty.
My current ones have acquired a slight bend in one point, but I am steering away from trying to straighten it. It may be possible to give the weak area some extra strength (but not much) by putting a bolt and heavy washers through the offending holes. Pre-heating the bolt would be even better, as it will tighten even more as it cools. I have not done this yet. You might even consider shortening the points a bit to reduce the magnitude of the bending moment that gets produced when a lateral load is applied.
A modification I made to improve soft snow traction was to take a pair of the aluminum crampons from Tubbs snowshoes, trim them to fit between the points of the Sherpa crampons, and bolt them in there (had to drill out some rivets on the Sherpas as I recall). I believe I also had to heat up and flatten out the "rocker" that was built into the Tubbs crampons, because the Sherpa crampons have no rocker.
In the end I actually don't use the Sherpas much, mainly because I tend to slice the lacing nearly every time I go out with them.
