We use US shoe-sizing. The width is standard-medium. They fit true-to-size. 
When ordering, if you are not sure about which size is right for you, please check the sizing guide below.
We know that there are full variety of foot types and for this reason we offer free shipping and returns and easy exchanges for 60 days after delivery of your order.
Walkny shoes are all natural leather and will stretch and mold into your feet with wear. The break-in period should take one to two weeks and the shoe will be fitting much better over time.
If you are still not sure what size to purchase, please email us at Help@walknyshoes.com including your foot measurements, the sizes and brands of loafers, slip-ons and slides you usually wear. We are Happy to Help.
