club foot

so i was informed at my 20 week ultrasound that my son may have a clubbed left foot. i recently got my 28 week ultrasound (a little late i was 30 weeks when i got it) and they told me his left foot does look clubbed and put down that he may need a boot ): i keep googling clubbed foot but they show severe cases and i cant seem to really find what a boot would look like for only one clubbed foot. anyone have any experience with a single clubbed foot?
