Belive me the front laced ones work.well. the laces are not speed laced they are corset laced which takes longer to do. Plus keeping her legs spread to lace them up Since the are crotch hi.boots so it does take a while to lace up. Such extreme bootsSounds like she needs to find ones that have the laces on the inside of the leg like a zipper rather than up the shin to give her extra incentive to keep her knees open
She even at times makes me lace them to tease me when she.goes out
