Yes it's OK to walk on a broken toe.
When walking on a broken toe try not to bend your toes as you walk and it will be okay.
As we walk our toes naturally bend back and forth which helps us walk better but when you have a broken toe you should just try to lift your feet up and set them down as you walk without moving your toe.
So you may just need to change the way you walk to avoid pain or further injury to the broken toe but you should be able to walk some.
If needed you may want to use crutches to help keep weight off your foot and toe while the broken toe heals.
Just avoid strenuous activity that strains your toe when the toe is broken and have a doctor put a cast on the broken toe to help it heal better.
