What to carry
Buy shoes that grip wet rock and a shell that actually packs small. Everything else can stay modest until you hike often enough to know what you miss.
Trail runners are fine on marked paths if your ankles are happy. Mid-cut boots help in mud and scree. In wet forest, a shoe that drains beats a shoe that claims to be waterproof and then fills from the top.
Break footwear in on easy walks. Hot spots on the way up become blisters on the way down.
