Very interesting indeed, I've had no problems really on my F2's, only the iSonic.
@Waiting4wind:
For me, higher boom/long lines results in an even more slippery front foot. When you say moving the track backwards, are you really meaning backwards? not forwards? :)
On moving the lines further back, this is what I've been messing around with lately, I'm sure that it has helped any, but 'something' is definately happening :)
@Sailhack:
This is the natural reaction on my part too, problem is that chop WILL kick my foot out of the strap eventually. I'm not wearing the most grippy of boots, but they're fine on other boards. I've played around with different types of footstraps (currently I'm running the big broad NP-Formula thingies) and the problem is the same. Tightening the straps will result in me not getting the foot into the strap at all :)
@petermac33:
Creating a more narrow stance, interesting, that might actually do the trick! I'll try it out! As for changing the footstrap box, if it comes to this I'm getting a new board! :)
Thanks y'all again for the feedback, I'm somewhat glad to see that I'm not the only one with this 'issue' :)
Keep it coming!
