Tine to get ready for spring! The best thing about these almond-shaped toe ballet flats is that they are stretchy. I find that my feet are in need of recovery at the end of the day after wearing flats, leather or not, and I feel stretchy fabric may help. The insoles are made with memory foam. I have posted pictures with measurement of the sole so you can compare it to a pair of flats that fit you for the best shopping experience.
