Boston Super Grip Leather in Color Black | BIRKENSTOCK US。Birkenstock Boston Super Grip – Black Leather Size 39 (Regular/Wide) Purchased brand new and gently used for under 3 months in a kitchen setting only (about 15–20 hours/week). Always worn with socks. They were beginning to get nicely broken in but still have plenty of life left. Super comfortable for long hours on your feet, and the non-slip sole performed great in a kitchen environment. Selling because I’m no longer working in that setting. No scratches or damage—just light, normal wear. No box. For reference, I typically wear a women’s 8.5 wide. I also included a foot scan in the photos so you can see how they’ve started molding. Originally $160
