For some women and some types of fins/fin straps, getting the fin straps over the wrists may be difficult to do.
I have spring straps and my very small feet don't extend past the foot pocket (XS), so neither do my spring straps. I cannot get my hand through my straps, so if I must, I put my fingers through the straps and hold onto the ladder too. My grip on a ladder is not as secure as it could be, especially in rough seas. A fins-on ladder is so much more preferred.
Are your springs flexible enough to pull them down, below your foot pocket? Even if there's not enough of a loop to pass your wrist through when they're in the normal position to contact your heel, if you push them either up, or down you can often make a loop large enough to get your hand through.
