I've had British army assault boots, German army combat boots and Norwegian army M77 boots. All are decent leather boots, the British ones are a swine to bed in from new (if you're lucky enough to get unissued boots cheaply) and 2 pairs I had in the past both failed in the same place indicating a weakness in that area to me. The German boots are excellent, much kinder to the feet and being thicker multi layer leather uppers they're warmer. The Norwegian boots are definitely the most expensive, but I've had I think 4 pairs going back to when I was 15 and they're by far the most comfortable combat boots I've ever worn. If you don't mind the price tag of the M77 boots, I'd certainly recommend them, if you'd rather be frugal then the German boots are definitely worth a punt.
