These are Cavallo boots, The numbers on the box and inside the right boot are [10] [5] [46] [38] [61.751] My normal shoe size is 10, 10 1/2 or even 11 (these days) depending on style and maker. Back then I could still wear 9 1/2 paddock boots, so I'm guessing these are 10. I bought them in late 2000, before the trip, but they're basically pristine, unworn but once or twice in the house. Not broken in at all.
Going away again now. More work must be done before plumbers arrive and there's another load of laundry to a) hang out and b) start and then hang out.
