I've had the Merrell Oslo boots for a couple of years (this is their third winter) and they are still going strong. Warm, waterproof and comfortable.
They've been worn in rain and deep snow and have never let me down.
The only negative review I read about them was that because the side zip comes down quite low (like the Taiga ones in your link) then this can leak water in if you are in deep water/slush but that was from someone in the US who lived in such climes for most of the year IIRC.
Size-wise I would say they come up slightly large. I bought my usual size (6) and tend to need thick socks otherwise they seem a bit loose.
Shop around though as you will find them at bargainous prices if you are lucky!
