You can put some things that smells good in your shoes
Or wash your shoes once a months
Remember clean your foot everyday
Put a paper in the shoes

I hope these ideas can help your shoes' stinks smells can disappeared
My brother got same problems too
So he washed his leg everyday

You can put some carbon in your shoes for a few days then the smell will disppear.
but the important things is you should put more care on your foot,like wash it and make it dry.
