What are the poetic devices (figurative language) in the poem "Ode to my Socks"? How do they contribute to the meaning of the poem?

The very first line, “Maru Mori brought me,” sets a rhythm to the poem through the repetition of “m” and “r,” which seem to roll, not unlike the sounds of the entire poem. No specific rhythm dominates, but sounds link lines together, creating an inner beat.  The abundant presence of l’s and h’s and oo’s in the first stanza, for example, give the sense of luxury, contrasting with mundane topic of “socks,” a word itself consisting of pleasant sibilants of the “s” undermined by the vigor of the hard “k.” The poem uses images that appeal to the senses, such as  “soft as rabbits”  and “two knitted cases.”  Note here also the parallelism in structure that imitates the nature of the socks (always a pair).  This follows with the metaphor of “with threads of twilight and goatskin.”  Twilight and goatskin again contrast with each other (one ethereal and gentle, the other concrete and rough), reflecting the main idea of the poem concerning the beauty in something simple and useful.
