These shoes are true to size! I was hesitant at first because I’m clumsy and was worried they would be too heavy to wear all night but they are so light weight! They sell out super fast but if you contact their customer support they email you right away and will keep you updated as they get information on new shipments. So if they sell out don’t worry you can get another shot but you have to be fast! Their customer support is amazing and my favorite thing about this company!
