Thanks again all, Thought I'd post a follow up for what it's worth.
I went with the Five Ten Trailcross - a newish model with mesh upper, and a little more walking/hiking traction in the sole. So far, I like them, though I haven't seen how they'll do in more extreme conditions. They're great for a little wet, cold, muddy. I had to hike-a-bike over some steep crumbly sections and they held up well for that.
Several folks above mentioned the toe box being small/narrow, and I agree. I have wideish feet and these are right on the threshold of not working for me, especially with thicker socks. That said, I did a long ride in them today with thick wool socks and everything was comfy, just a bit tight.
I think the breathability will be amazing once it's not so cold.
anyway, thanks all for the recommendations, there were lots of good ideas on here, very helpful.
