[General Fantasy] What does a Pegasus do with its legs while it’s flying?

I can’t picture anything that doesn’t seem totally ridiculous. Do they just dangle limply and billow about in the wind? Do they hold their legs tightly underneath themselves like a sort of horse-loaf? That seems incredibly uncomfortable to do for extended flights. 

I know some media portrays them as sort of galloping at the air while flapping but that can’t possibly be the case. Galloping requires solid ground to push off of so in mid air the Pegasus would just be flailing its legs futilely (which we have to imagine would unbalance the hell our of it as it’s trying to fly). 

So what does it do with its getaway sticks while in the air?

The winged horses are of divine/magical origin.  Their hooves allow them to gallop on the air.  The wings are used for altitude and stabilization, but they are still using their legs.

Legend also has it that their hooves have a magical effect on the ground as well, creating water springs where they step.
