A bunion wrap is a type of supportive device that is worn around the foot to help alleviate pain and discomfort caused by bunions. They typically consist of a padded splint that is placed over the bunion, and an adjustable band that wraps around the foot to hold the splint in place. Some bunion wraps also include additional features such as a toe separator or arch support. They can be worn during the day or at night to help reduce pressure on the bunion and improve alignment of the toes. It's always better to consult a doctor or a physical therapist before using a bunion wrap or any other kind of supportive device.
