I really shouldn't ask as I think I am sorted but since the price is so good would be interested in your feedback when you get them, including on sizing. Vibram soles are really good.
First impressions are good. Size 8s actually fit, I've got a wide fitting foot and they fit. The soles are as expected. I've not fitted cleats yet (none spare and loathed to buy any because I need new pedals). I bought them with a view to using them on my MTB with flats.
I've walked around in them for a few hours atbhome and driven in them they better for driving than my other cycle shoes and better for walking in than most.
I might we'll take them on holiday as my only Cycling shoes and may end up using them for non foul weather commuting.
They're not light though. Not tried the waterproofing yet but in expect the usual cycle shoes problem (two big holes where your feet go in). Needed re lacing to make the laces pull tight.
All in all pretty chuffed and my thanks to the OP.
