Most tourists who use toe clips never tighten the straps. This makes entry and exit very quick and easy. I can get my foot onto the ground during a slide on steep gravel and can get my foot back into the clips every time without looking.
The usual footwear would be a lightweight trekking shoes, the sole is stiff enough for touring use. You need racing stiffness in the shoe if you are going to apply racing force, something I never do.
Expedition tourists heading far from bike shops should be aware of clipless failure modes:
worn cleat- failure to exit.
cracked sole- failure to enter pedal.
