Wait a minute...
He remembered when he took Lou Fei'Er and jumped into the snow layers to find mutant humans, and a snow leopard surrounded them.
Its enormous body walked on the one-meter-thick snow surface without any tendency to sink, walking like on solid ground.
... Can all these snow creatures move on the snow surface?
Snow foxes should be able to as well.
Snow foxes are small in size and weight, naturally they wouldn't sink into the snow.
Don't be fooled by these seemingly soft white layers, under the nighttime temperatures of negative twenty to thirty degrees, the accumulated snow will become as solid as ice shards. Although it can't support human weight, for the size of a snow fox, moving on the snow surface shouldn't be a problem.
Generally, foxes walk on the snow to forage in winter, then leap up and dive headfirst into the snow to find prey.
Just not sure if they can still successfully hunt with such thick snow layers.
