Good to start with, 15 May 2013
No problems initially ,on first test walked for hour and a half mixture of wet grass mud and flat track boots coped ok for a lightweight design.
Rinsed them off left them overnight to find them soaked through in the morning .
Obviously the water seeped in overnight .
Will be taking them back,don't buy for anything other than the local park in the dry

I'm not one for completing reviews under normal circumstances, but so impressed am I with this boot I feel compelled to share my experience.
Until now I've been strictly a Salomon, Inov8 and La Sportiva compulsive.
My decision to try something different was largely born out of feeling let down by the Salomon Speedcross and Fellcross shoes in the wet. Neither is very good on wet rock, and of course they are a shoe opposed to boot, so regardless of any Gore-Tex qualities they may have, that won't stop water coming over the top. I needed a boot. I've got a pair of La Sportiva Trango Alps alpine boots, but they're too rigid for British hill walking in the summer.
In terms of sizes, I have odd feet by a good half size. I would say my left foot is a size 8.5 and my right 8.
In Salomon Speedcross and Fellcross I take size 9, in Inov8 X-Talon size 8.5 and in La Sportiva size 9 (all UK sizes).
In this boot (Mammut Cirrus) I went for a 9. The fit is perfect, plenty of room at the front of the boot so my toes were not banging off the front of the boot coming down hill. The fit was still snug, so no 'slide', which might cause blisters.
I wore them straight from the box over two days (20 miles each day) in the Derbyshire Peaks. I deliberately threw everything I could at them to test them. I wore them with a pair of Berghaus 'ice' ankle gaiters.
Through deep mud, peat bogs, shallow rivers you name it the boots didn't leak a drop. When water came over the toe box I got a cold sensation through the mesh material but it didn't breach the gore-tex.
They were instantly comfortable, I wore them with a double lined 1000 Mile sock and didn't get a single blister.
So far as the grip was concerned, once I'd worn them for about 10 miles and scuffed the newness from the soles, they performed better on wet rock than the Salomons.
The only thing I didn't really attempt was running in them due to the weight in the pack I carrying it wasn't really an option.
The angel hair laces might not last too long and my intention is to keep a spare pair of laces in my bag just in case they snap when you least need them to. If that's the only downside, then I'm more than content I've found a good boot.
Overall, I was extremely impressed and would highly recommend them. I would however recommend you try them on for fit before ordering via the internet to be 100% happy before purchase.

Love the fact its an approach boot but also very handy as it has that trainer look to it which makes it suitable for a everyday walking shoe, worth the money and holds out the rain very well with the GTX.
