Ok, so I checked last night. I have been putting it under both inner & outer cuffs. The strap is not mounted too high. I think I am not tightening the buckles enough & once the boots flex, the edge of the booster strap gets hooked on the shell & gets forced up & out of the way.
So now should I modify the innermost cuff to make room for the strap? Or I was thinking about just tightening everything more, but removing one or both screws on the rear cuff to allow the boot to flex more. I really seem to like the softer flex, hence my buckles are too loose to hold the strap.
