I've used the Nepal Evos for alpine winter stuff - for trips that start and finish in a warm hut they have been fine. So long as they're not too tight and you have some nice thick socks I'd save yourself the pain of buying more boots. There are plenty of shops in Chamonix who will relieve you of a little cash if you want to upgrade after your first outing. Enjoy the Frendo, it's awesome.
