A bunion is a bony bump that forms on the joint at the base of your big toe. It occurs when some of the bones in the front part of your foot move out of place. This can be genetic, caused by arthritis, or from wearing shoes that were too tight. People with bunions should look for shoes with an expandable toe-box and a wider base to accommodate their toes and bunion.If you're new to Pandere, we suggest you let us size you before buying so you get the right size.
