Unisex vintage zucca slip ons are in great condition for their age. There is no size marking as these are vintage and that marking has faded. They will fit a women’s size 7.5-8 or a men’s size 6.5. I wear a size women’s 8 to 8-1/2 and i was able to get these on. They were tight on me, but that is because i have a high instep. Please see all pictures for condition.
