Lanvin paris curb cap sneakers

I have a pair of brand new never worn LANVIN cap toe sneakers in sz43 eu which is a men's sz 9 us. I took them home, took them out of the box, put them in display with the rest of my shoes and just.... never wore them. So now it's time to clean out my closet and put some new shoes I'll probably never wear in their place? Anyway, I no longer have the box but if needing them to be shipped I will find one that will fit them appropriately to ensure their safe and sound journe to their new dwelling. Price is $990.00 originally asking $550obo
