I often walk barefoot (often times all over !!) depending on the conditions - when going on day walks I will have a pair of sandals (usually Tevas) for when the tracks get rough and sharp.. For overnighters, or cooler weather, adding a pair of shoes as well - boots are only really needed for more extreme conditions, or multi-day expeditions...
Down here (on the East coast of New South Wales..) for much of the year any clothes in general are an unnecessary and extraneous part of your kit, (at least once you get away from "civilisation") - maybe 2/3 to 3/4 of the areas I frequent could be approached and traversed barefoot or in sandals; while for about 8 - 9 months of the year around this region (: September - May ..), I only need (minimal) clothes at the beginning and end of the walk.
Having said that, however, I will :
* wear the essentials - hat, sunglasses, sunscreen and insect repellant;
* have sandals (on my pack..) for daywalks, plus shoes for longer walks;
* carry some protective clothes - depending on how bad the weather could get;
* have some ('minimalist') clothes ready (in my pack..) for when I may have to pass by - or through - a well populated or trafficked area - a light skirt or sarong, and maybe a light shirt is all that's really needed in most places..
