Birkenstock Boston Sherling in retailer Night

Product Name: Birkenstock Boston Sherling in retailer Night
Ladies size 40 US size 9 Natural Cork footbed Narrow/Medium fit Suede Shearling lining Color is “Night” a navy blue with blue shearling retailer inside Great preowned condition. There are just a few little blemishes on the shoe. A little white mark on the bottom of one. Please see photo. I only wore a few times. You can see where the lining connects to the sole of the shoe around the cork. This is just where it connects and I have seen these same shoes on Poshmark with this same appearance. These shoes have literally been worn like a handful of times if that so it's not from excessive wear. The last few pictures show what I am describing. * sells new for $170. Open to reasonable offers.
