Ice Freezes at What Temperature
As long as Todoroki kept the ice’s temperature just below 253 K(-20°C), this is more than enough pressure to make it flow without melting. He could also stop cooling the ice in places where he needed it to melt and flow around a barrier before resolidifying.

Can it be too cold for ice?

The ‘excess’ vapor condenses out into a cloud. “At very cold temperatures, the expansion cooling process starts in air that already has a low water vapor content. … There actually is no such thing as too low a temperature for some sort of ice crystal to form and for such crystals to settle out and land on the surface.

Can ice be colder than other ice?

The temperature of ice varies just like the temperature of any other solid substance–within the physical limitations of its solid state. Just as the temperature of water varies between 32 (degrees) and 212 (degrees) (its freezing and boiling points), the temperature of ice ranges from 32 (degrees) downward.
