I went out for a couple of test runs this morning, and there was no way I was going to survive the day; being on toe-side just hurt like hell, and my turning was really awkward. So, I've decided to call it a day, head back to the chalet, and chill out. Otherwise I'll probably just hurt myself more.
Ah well. It doesn't feel like there's any long-term damage at all, so I guess I did better injury-wise this year than last year :) I'm definitely getting a lot better at boarding, with no major falls and a lot less falling over in general. I'm more confident, especially when there are other people nearby; a piste no longer looks blocked to me when there's a ski school in front of me, because I'm good enough to aim for the gaps now...
Notes to self for next year:
Boots: Salomon 27.5, but see if you can find something with better heel grip
...and get some bloody practice turning and stopping and otherwise manoeuvring with only one binding in, because it's ironic only to injure yourself when getting off a bloody chairlift..
