My Vuelta Corsa Lite wheelset from Nashbar, which I got on sale for less than $200 shipped, has quite a loud hub, actually almost as loud as CK hubs. But I still find that they don't do much to let people know I'm behind them.

I will also still be looking for a winter shoe solution this year. Tried many failed attempts last year with my normal MTB shoes. I have different shoes I use now but they're even more ventilated than the MTB shoes were. I will try the aluminum tape under the insole idea. Problem is they're not all that wide for using more sock layers. May need to get some shoe width stretcher devices or something like that.
