Tuesday (8/18), after a likely mixup on the dock, I wound up with a pair of Grition brand sandals, Euro size 43 (apparently equivalent to U.S. men's size 9.5-10)
These look a lot like my own Keen sandals, which I was unable to find after my row.
A pic of the Gritions should be attached here. Let me know if these are yours, and if you might have my Keens as well.
Thanks!
