Hi Sorefoot,
I am in the same situation as yourself, However my right ankle smashed over 15 years ago. I have never snowboarded, but used to skateboard, but had to give this up. I'm very keen to hit the slopes as my wife is a keen skier, and I always miss out as I can't find a boot that works.
1)How did you get on? Did you find a way to get round the lack of movement?
2) Also my right foot would be my front foot on the board and understanding this helps me as there is less movement required? Is this correct....
Any guidance would be great.
TIA
