I've been having issues with my front foot coming out on one particular board when using 2 out of the 4 sails I normally use with this board.

I've tried all the usual things to remedy, lower boom, tighten / loosen / move footstrap, move harness lines but to no avail, yesterday I tried something different in an act of desperation.

I swapped over my standard front footstrap for a set of adjustable Cabrinha kite board straps, the big wide arzed looking things.

Straight of the bat this was a winner, my foot felt secure without feeling trapped, the strap was SUPER comfortable and still allowed for easy trim of the board.

During the rest of the session there was no further front foot issues, I even started raising the boom again with no problems.

Hope this can help someone else
