What's the demarcation line between boots and shoes?

I've got a new pair of one or the other, anyway, made here in New Zealand by McKinlays (who reckon they're boots). Proper old-school footwear - made to last.

I discovered that if a style is listed as Made To Order, McKinlays will make them up in a non-standard colour at no extra charge (though they then won't be returnable).
