Relating to or involving the hallux, which is the medical term for your big toe.
From Latin hallux meaning 'big toe,' combined with the adjectival suffix -al. The Latin origin of hallux itself remains uncertain but may relate to ancient anatomical terminology.
Your big toe is actually incredibly important for balance and walking—hallucal bones and joints are what push off the ground when you walk, which is why big toe injuries can really throw off your gait.
