Mammut T Advanced GTX

A very comfortable shoe, with a hard enough sole to protect your feet on hard rocky terrain and a great ankle support. Great for hard trekking.

FIT:

I bought these on an internet store and the fit is perfect. As soon as you put these on, you feel your feet very comfortable. I've used these with one pair of socks and feels great, but when needed I can put a second pair of socks (thick merino wool) and by loosening a little the laces, it feels great again.

COMFORT:

Yes, they are. BUT after a 10-hour walk on the Ventisquero El Amarillo I ended up with some blisters. I think I could have done better by re accommodating the socks every hour and using a more breathable material on them like Merino from the start.

SUPPORT:

Walking on a very rocky snowdrift I missed a step and bend my ankle very bad, but this shoe kept it very well. Nothing more than the scare (I was afraid of an injury), I was able to keep walking without problem. Also going down a volcano, the ankle feels very secure on those uphill terrains. 

WATER RESISTANCE:

The GoreTex does a very good job. Crossing a river makes no problem.

TRACTION:

The VIBRAM sole it's very grippy and rigid for walking on rocks that other way will make your feet feel very hurt (volcanic rocks specially that are sharp and with sizes that when you step on them you really feel it).

TEMP CONTROL:

As I said, I think that you could feel these a little too hot in the summer, but I find this to be a small detail against the pros mentioned above. 

FEATURES:

I think it's worthwhile mention the "memo foam" that stays very cushioning.  

CONSTRUCTION:

Very well made. It's really far above the previous The North Face I've own before. 

CONDITION:

Used on the snowdrift "Ventisquero y Glaciar El Amarillo" on Pumalin Park on a 10 hours walk and up to the Chaiten Volcano as the hardest uses. They are rock solid.
