NWT Prada black suede loafers

Authentic Prada shoes Black suede with gold chain detail Loafer style with chunky heel Square toe Prada box included Worn around house to try and stretch- unfortunately unable to. Slightly small Prada typically runs a half size small. I would say 8.5-9 comfortably. Says EU 40 which should be a 9.5 but that is very tight
