My cold-weather minimal shoe solution is the Teva Proton water shoes with thick wool socks. So far, this seems to be working pretty well--not quite the same as VFFs, but much warmer and still not a clunky shoe. I can also put Stabilicers Sport over them if necessary for traction, and can even use short gaiters with them to keep out snow. I wonder how those Feelmax shoes are--does any store in the area carry them where one could try them on?
