Is it easy for Adidas shell heads to turn yellow? I see that the most popular comment is that the shell series turns yellow. If you know, please tell me. Thank you.

The shell toes turn yellow very easily. When I went home during the summer vacation, I left my shoes in the dormitory for two months without wearing them or putting them in a shoe box. The toes oxidized. When I took them to a shoe cleaning shop, people said No washing. Later, I bought the deoxidizing magic on Taobao for more than 30 yuan and washed it off a little. Although it was not as good as new, it was not too yellow.
