Hey Dutchie... Are you Dutch? If so I can confirm that the former Invisible shoes perform excellently in the snow. The Truefeel soles are rough on the inside unlike the Vibram outsoles so that your feet do not slip. I have run last winter over packed snow and ice and it's a gas.
I assume that you are already familiar with huaraches or barefoot running in cold weather, in case not: your feet will in no way freeze. I have had more problems with cold feet running in normal trainers than with the huaraches... I even had to strip off my in Injinji socks!
The grip on even slippery footing is amazing, and when I use the term 'grip' I really mean it, because this is exactly what your toes do!
