psychle.. have you seen an MX140 in the flesh? There really is very little to them. It's just a neoprene sock with like a plastic sandal around the outside. I'd imagine good for wet summer rides, but not so hot in the middle of winter.
After many winters, my Answer Kashmirs are pretty much shot, and am looking about as well. I think the Lakes mxz302 would be my first bet, although I am a little peaved they don't have the wide fittings over here! Then it would be the Northwave… although I am tempted by the cheapish Diadora boots on sale on Ebay at the moment…
EDIT: although saying that, I have just found that All Terrain cycles seem to have the wide ones in stock…
