RE: Changing footstrap settings for the day
Well, just for the records, I believe that most sailor don't change the straps position ever. I include myself in that group once I find the best option. However recently I did it to be able to get some sailing on my iS105 and 4.5 sail in 25+ knots (I'm 67Kg) in heavy chop.
Changing the straps to all the way forward allowed me much more control over the board. Even if it was clearly the case of a much smaller board which I do not have, still it allowed me to have good fun.
So definetely changing the straps position is something to consider at times.
