BIRKENSTOCK Montana model, red and black combination, size 36. - Brand: BIRKENSTOCK - Model name: Montana - Size: 36 - Color: Red/Black Thank you for viewing. This is a special edition color, and I believe the stock quantity was limited. I cherished these and didn't wear them much, but they don't really match my current style. I've decided to sell them to someone who can wear them fashionably, rather than keeping them stored away. I think they'd be great for adding a pop of color to your outfit. I think these can be worn all seasons! Thank you,
