Hi. My DS has broken his big toe and was put in an air boot about 2.5 weeks ago. At a recent hospital appointment they said he needed to keep it on for another four weeks and will then be reviewed again. He has a Duke of Edinburgh expedition scheduled four week and two days from now? If anyone has had broken a big toe or their DC has, would you/they have been able to go on a five day hiking expedition very soon after the air boot comes off??
