socks

彼女は靴下を履いていても足先が冷えている。割と長い厚手の靴下なんだけど。

She has cold feet even though she is wearing socks. It's a relatively long and thick sock.

彼女の靴下は脱げて落ちていたのをを帰り道に見つけたり、彼女自身で脱いでしまったり、大切なのに儚い扱い。

Her socks were taken off and found on the way home, or she took them off herself, and treated them as important but ephemeral.

歩く前にサイズアウトかな。

I think it's out of size before walking.
