This might seem like an odd suggestion but Ive ridden a few times in these babies over the winter: http://nativeshoes.com/ca/adult-boots/jimmy-winter-jiffy-black-solid-plaid (the name is just coincidental)
They are lighter than pretty much any other shoe and stick to flats incredibly well not to mention totally waterproof. I even modeled them for some of the nsmb boys during parking lot beers last sat on Seymour.
They looked sweet right guys??! lol
They looked good to me as post-ride shoes but very thin and light for actual pedaling. However if they work for you, that's great.
Mic I think you got sorted but here's my review of the Giro Alpineduro: http://nsmb.com/giro-alpineduro-winter-shoes/
I used them again this winter and they were great, although I've been riding more on flats and this is my new go-to for winter conditions or otherwise (for flat pedals only, unfortunately): http://nsmb.com/own-fr-01-shoe-review/
