Eczema Treatment Care

i have taken contact dermatitis from a new pair of shoes and wondered if anyone had the same problem

i suffer from contact dermatitis on my feet and allergy testing has shown i am allergic to leather and a rubber called mercaptobenzothiazole (MBT), so i need to find shoes that don’t contain either of these things.
impossible so far!!!
i’ve tried clarks, scholls and they contain mbt
any help appreciated!!
thanks
