Clack Klan Women's Flats - Size 8.5

Selling a pair of Clack Klan women's flats in size 40. Only tried on indoor, too big for me. there’s a darkened spot at the insole because I tried to put a self-adhesive insole to make it smaller..didn’t work. The shoes have a unique checkered design with a black toe cap. Super comfy (same as vivaia) and classic for office or casual day out. I am a size 7.5 in most brands (Tory, RV, Sam Edelman, JC,etc) 8 in Steve Madden, this pair fits US 8.5 to 9.
