I broke my ankle for two reasons.
Firstly, soft snow made me overconfident as I was able to carve faster and tighter turns and thus pushed my equipment and body to limits beyond my ability. As they say in racing, I ran out of talent.
Secondly, the equipment we are using is getting so much better that we are able to turn harder and faster than before, again allowing us to carve faster and tighter turns putting us into difficult situations that we were never in before. Most of my older boards had stiffer flex patterns which did not fold on soft/spring conditions. For a while, boards were built with too much flex at the front of the board. I think the newer style boards have less flex in the nose and more between the feet with will reduce these accidents in the future.
I think these two factors increase the injury dramatically, as I think we have seen more posts of injuries this year than in the past.
