Will soon be changing all four boots as they have naturally reached end of life at the same time. I don't really drive round like a bat out of hell any more - quite the opposite in fact. Now just looking at quiet, good grip in dry and wet and doesn't require a mortgage to buy. I've been happy with the 2s and 3s so I will take a punt anyway but just wondering if anyone has any experience of these so far - I think they are quite new. Not fussed about alloy protection per se but if it's there then fine.
