Northwave do an ‘artic’ version of their winter boots which has a fleece lining. I wear mine all the time from now until easter as they’re breathable but keep the mud out as well as the cold.
Their range seems to have grown somewhat but the raptor gtx artic looks like the closest comparison to my old celcius boots. The ‘husky’ boot looks like a Celsius in cheaper materials?
Either way, they’ve been by far the best £150 I’ve ever spent on cycling kit, makes winter riding completely normal (with Roubaix longs, waterproof shorts, a half decent top and a buff).
