2018 Corolla Shift Knob

I changed my shift knob out to this one below and cant seem to find a way to keep the boot/gap from falling. Is there another method or adapter that will make the boot flush with this type of knob not having to use zip ties or double sided tape which looks tacky and doesn't work? Any help to make this knob stick flush with the boot will help me out tremendously.
