In reply to jockodiounto:
Mantas are great boots. When I climbed Orion Direct, my mate I climbed it with was wearing a pair, fair from ideal though.
Nikwax Wax for leather will help keep the water out, as will a pair of Gaiters. Alpkit Colca Gaiters are very good value.
Crampons: G10s will work okay on both pairs of boots but Zodiacs aren’t really designed with crampons in mind. I would get a pair of Petzl Vasak which will take you from winter hill walking right up to to very hard mixed and ice climbs. The Vasaks are lighter, more versatile, and cheaper than the G12.
Enjoy your first steps out in winter
