I loooooooove these and was hoping the 40 fit but no. I’m a true 39. 8.5-9. These are more like 9.5-10. I have these in gold and white, dark pink and green. They are so so fun, make you feel happy and just a bright pop of color and unique. I get compliments at least five times a day when I wear them. I only tried these on. Thank you friends. Questions?
