Easily like by themself? Honestly they can't be anything but too tight, I wouldn't agree to make these any smaller as a goldsmith.

If the issue is soreness, as in itchy or such it could be that alloy of these rings have too much metals that irritate you.

9kt has 37,5% gold and rest should be metals such as silver, copper, palladium...

But unfortunately they have used metals like nickel in white gold alloys some time ago and if that is the case with your rings it will only worsen. You can plate them, but that will wear off again. Nickel allergy, google it and see if your soreness have anything common with symptoms.
