Better with snow shoes than just boots, you used to be able to hire them for about 8 euros a day from Snell but that was a few years ago now. They are really easy to use and carry and make moving around much more pleasant.
Or just buy some if you are out for a week plus as it won't cost much different. I picked up some in Technique Extreme that were pretty cheap and functioned fine.
Actually there's been massive snow fall a few weeks ago, it's just all the lift accessible snow has been tracked out and compacted. Anything not skied will still be post holing hell.
In reply to GridNorth: I was out in Chamonix the week after Christmas and hired some snow shoes from Technique Extreme for 5 Euros a day. There was plenty of snow and they worked well when I used them on the Valley Blanche and on a couple of other days out.
