Hoka Carbon x 3 racing shoes. Size 7.5

Size 7.5 running/racing Hoka shoes. They are Hoka Carbon x 3. They are mostly white and orange. They have blue and maroon as well. They were purchased on 8/11/2023 and have 98.66 running miles on them. Were worn in 2 marathons and a few 5ks. The rest were training runs prior to a marathon. They have some brown spots on the white from a rainy 5k. I tried to wash it off without any luck right afterwards.
