Trying to create boots that can walk on powdered snow

To make the armor resist freezing like leather armor, you can add it to the 'freeze_immune_wearables' tag.

The powder snow walking is a little bit trickier. Once you're finished with the armor you need to lock the mod element, and open the Java file. In the top section, where it lists all the imports, add this between any of them:

import net.minecraft.world.entity.LivingEntity;

Then Find the part about the boots, and add this after the first @override. (Make sure it compiles correctly!)

@Override
  		public boolean canWalkOnPowderedSnow(ItemStack stack, LivingEntity wearer) {
  			return true;
  		}
