When combine the constriction from the neoprene with the less room left inside of the shoes for the feet, further constricting blood flow, you are going to be left with cold feet. Put the neoprene outside the shoe, not inside it.
Good points to consider. Hopefully if I can find the right shoe/boot I won't need the neoprene at all anymore. For what it's worth though, when I'm XC skiing I use the same neoprene socks inside my Rossignol XC boots without any problems at all. Also as an aside, I found the Rossi XC Ski boots to be surprisingly passable as biking shoes when I've worn them biking to our nearby golf course to go XC skiing. I even thought about using them as a winter bike boot, but I do want to have Spd cleats so that rules them out. Hey there's a thought for another thread on some other forum: "Wanted: Spd-XC ski bindings". Hmmm. Anyway thanks again for the good points on blood flow.
