Early last winter I was wearing my Vanson Enfield, carrying a big box and tried to squeeze through a narrow corridor, my shoulder was rubbing against the white wall, I could see very obvious color transfer. And it was not a hard rub.
Yup.. accidently brushed my bull nose corners in my house same thing. Heck, the aero cordovan cr was leaving marks on the dry wall in the closet from sleeves brushing it taking it on/off hanger.
But I just have to wear them inside when breaking them in... yes I'm a dork lol
