Why does water sometimes make things slipperier (e.g. hydroplaning) and other times make things “stickier” (e.g. putting socks on wet feet)?

Hopefully the question is clear: basically, why is it that water on roads decreases friction, and water on a floor can make it easier to slip, but water droplets on feet make putting on socks harder?

Aquaplaning specifically is caused by there being too much water for your tyre to displace. At this point the tyre isn’t in contact with the tarmac at all, but only with the plane on water between it and the tarmac hence aquaplaning.

Water on a road surface could also act as a lubricant without causing aquaplaning but that is a different scenario.
