My partner and I tried the Chota mukluk for an eight day trip in Quetico in September.  We were both quite happy with them with these provisions:  get a good support liner such as Superfeet, etc and get their more recent models that have a stronger webbing holding the lace in place.  
We both found them to be warm and comfortable with good traction.  At one point I was hip deep below a beaver dam, filled the boots with mucky water and found that, with a semi-warm day and a breeze, they dried out enough over night to be comfortable again the next morning.
Two thumbs up, so far.
