Get Your Feet Wet
= to get a little first time experience doing something
(Imagine a cold or hot pool. Instead of jumping straight in, you dip your feet to get a better feeling of the temperature, and after you might jump in.)
Ex: Before you start the new job, do a little training to “get your feet wet.”
Ex: The food is extremely spicy, so “get your feet wet” by trying a little bite at first.
