A deformity of the big toe joint in which the joint becomes enlarged, stiff and often painful.  The area can become red as shoes rub over the enlarged area.

The big toe often moves towards the 2nd toe and in the medical profession is known as Hallux Valgus.  

This deformity is more common in women than men and often associated with Flat Feet and can run in families.  Wearing unsuitable footwear such as very high heels and pointed toe shoes can be a factor in their development.  Arthritis and gout are other known factors that increase risk of development.   

Tailor's bunions are lesser known but also fairly common - they are similar to regular bunions but smaller and form on the outside of the foot at the joint just behind the little / fifth toe
