A condition where there is an enlargement of the big toe joint of the feet is what we called the Bunions. Technically they are a part of what is called hallux abducto valgus, which is when the big toe (hallux) leans over (abducto) towards the lesser toes and twists (valgus). The bunion happens when t big toe joint protrude outwards. Bunions are not necessarily caused by shoes which are the common belief, as those who never wear shoes still get them. However, it is only in the shoe wearing population do they get painful and get much worse. The shoe provides the pressure to make it progress much quicker.
