I'm after a bit of help about the Dakine x lace foot straps - who uses them ?

I just bought a great 'brand new' pair with the intention of fitting them to a surf board that I'm hoping will arrive soon - but noticed they are slightly asymmetrical ie not ideal for a surf board as I jibe most turns.

After a Google search I'm non the wiser !! . - A lot of the search results say the x-lace is symmetrical ?? The ones I have aren't :-(

Are they or aren't they?? - Ok I know they aren't !! I'm not comfortable fitting these !!

So I guess I should 'on sell' these ones and chace up some symmetrical ones ?? Or has anyone fitted these (asymmetrical ones) to a Kitesurf surf board and found them OK ??
