Rothys Clementine Drivers - size 10.5

Clementine Drivers size 10.5. Bought these second hand before realizing that I need a size 11. Smoke free home. I haven’t washed these bc I just tried one for size and realized they are too small. Im happy to wash them and the inserts before shipping if buyer wants me too. I‘m fairly new to Rothys so I’ve never washed before is my only hesitation. I don’t have box bc I bought them second hand.
