Find two implied metaphors in "Velvet Shoes." VELVET SHOES

let us walk in the white snow
in a soundless space
with footsteps quiet and slow
at a tranquil pace
under veils of white lace

i shall go shod in silk
and you in wool
white as a white cows milk
more beautiful
than the breast of a gull

we shall walk through the still town
in a windless peace
we shall step upon white down
upon silver fleece
upon softer than these

we shall walk in velvet shoes
wherever will fall like dews
on white silence below
we shall walk in the snow.
