In reply to joepowellll:
It could be cold and it will almost certainly be wet underfoot if not in the sky, so winter boots may not be overkill in that sense. For decades people did big walks in clumpy leather boots, and enjoyed themselves. I guess they're heavier and stiffer than you might ideally prefer for long days of walking, but on the upside the stiffer sole will give good support on rough ground and with a heavy pack on you might appreciate that.
The big thing that trumps everything else is fit and comfort. Do you think you can wear them for long days of walking back to back, without issues? The fact that you love them suggests they're probably a good fit, but feet do spread over a long day (potential squeezing round the toes) , and soften if they're too warm for too long (blisters). The best idea would be to wear them on a couple of proper meaty trial days, if you can get out in the next few weeks.
