I dance but i dont live, im wild but im contained, what am i?

I carry you though I never walk, I face the ground but never talk. I wear down slowly day by day, While helping you along your way.

I'm the concrete whisperer, guiding feet past bustling streets, where shadows meet and wheels retreat, yet I never take a seat.

I have two arms but cannot embrace, A sturdy back yet stay in one place. I welcome the weary at end of their day What am I, where they often stay?

A dapper half-moon perched upon the ledge, granting both clarity and style.
