Birkenstock Birki’s rainbow spring slides

Birkenstock Birki’s rainbow spring slides, in good to fair condition. Birkoflor top, some wear to cork, but lots of tread left. Edges of cork and tread have very slight separation at edge, but probably quick fix with superglue. Selling as is. These would be great to have for the garden, boat, garage where you don’t have to ruin nice sandals but will have the comfort and support of Birkenstock. Size ha worn away, but based on measurements I think these are either 40 or 41 regular, but please see measurements for best fit. Please review photos and ask any questions you have before purchasing.
