Birdies offers a fit guarantee as well as a 30-day trial period for US customers. This means that you can try on your order, wear them around, and make sure they’re your perfect shoe before committing.  If you don’t absolutely love them, you can return them for a full refund; this also includes free shipping for returns.  They even offer “Happy Returns,” a more eco-friendly return option. Simply drop off your Birdies at one of their drop-off locations to skip shipping. See full details on Birdies return policy here.
