Men’s Sperry top-sider canvas shoes Sz 7M

White canvas Men’s size 7 Sperry Top-sider Shoes. My son grew out of the fast! They are in good preowned condition. On the inner right shoe, by keyholes there is a light yellowish discoloration & I have not tried to get out (see photos). It may come out with lemon juice and baking soda.Other than that, they are good:-) Thanks so much!!
