How do I stretch Lanvin flats?

To stretch Lanvin flats, buyers have suggested online that wearing socks within the first few wears around the house is a productive measure. Wearing the flats with socks is believed to help apply much-needed pressure to the elastic in the footwear. Lanvin flats do give a bit and will eventually mold to better fit the wearer’s foot after a few wears. Online reviews indicate that Lanvin flats do tend to run small by about a half size (consult the size guide on the brand’s official website for more info). Find vintage Lanvin ballet flats on 1stDibs.
