Anyone had anything to do with these boots?
I'm trying to establish whether they run narrow or are on the wider side.

Not tried them. I've heard they run narrow. They're made by / based on Raichle.

I love mine. They are wider in the toes and narrow in the heel. I have pretty wide feet and high instep and they fit me better than any other boots I've tried. They are much wider than La Sportiva, narrower in the front than Scarpa Mont Blanc. I wear 11.5 in street shoes and 12 for running - size 13 Mamook is just right for me.

I don't have the Mamook but the Mammut I have runs wide compared to LS ( a lot wider) and Scarpa (some what wider and more toe room). Fairly big toe box in the Nordwand I have. And narrow heel as reported above. I have 12 and generally use a 11.5 or more likely a 12 running shoe and I am using a pair of 12 Nordwands. These fit me well. But IMO a very old school, two pair of wool socks, kinda fit.

I have the Mamook Thermo. Also have the Mammut Pacific Crest GTX. My foot measures 9.5 with normal width and I wear a size 10 in both.

I find the fit between the shoes very similar. The only fit issue I had with both shoes was the shoe width immediately before the foot box, in the widest part of my foot was a bit narrow. After wearing the Pacific Crests for quite some time, the shoes have opened up. The Mamooks are newer and I find they're slowly following suit.

I have the Mamooks and the Nepal Evos in the same size. The Mamooks crunch my toes a little bit (not just because they're too narrow, not much volume in the toe box), so I tend to only wear them when I'm roadside cragging on difficult stuff. I find that the Nepals are just as good as far as heel rise and control, as well as having more room to wiggle my toes, so I tend to wear them much more.

Thanks for your replies, all I need to do now is see if I can get them in Australia.

Has anybody worn the Mamook Thermo? It's rated to -35 C but I'm thinking that's way too optimistic?

I'm also looking at the LS Batura, which would be warmer at 5500-6000m?

Yes, I have them, and dearly love them. I wrote a review on Backcountry:

In a nutshell: warmer than the Trango GTX, about as warm as the Nepal EVO but not the Batura. Fit is very true to 'real' size (eg, fairly tight) so they excel at waterfall ice climbing and mixed, but these are not warm enough for big ice peaks IMO; for rock or mostly rock to 5000m they would be excellent.
