Sensible describes a person or a choice with good practical judgement — no drama, no showing off. Boots when it snows, leaving early for the airport, the friend who takes your car keys after the third drink.
It fits people and choices alike: a sensible woman, a sensible arrangement, the sensible thing to do. Sensible shoes are the flat, comfortable, unglamorous kind, and the phrase is half a joke. Here is the trap: sensible does not mean sensitive. If your language has a word like sensible for someone easily hurt, English uses sensitive for that, and calling a grieving friend sensible will puzzle everyone in the room. One old formal use means aware of — I am sensible of the honour — but you meet it only in old books. The adverb is sensibly and the noun behind it all is sense.

Latin sēnsibilis meant able to be perceived by the senses, built on sentiō, 'to feel, to perceive'. English took it that way first: a sensible difference was one you could actually notice. Only later did it slide to mean having good sense. French and Spanish stayed closer to the older road, which is why sensible in those languages means sensitive, and why the word trips up half of Europe.
