Best mammut mountaineringboot? - Mammut Eiswand GTX Mountaineering Boot - Mens

I bought these shoes on my holiday in Switzerland for discount, normaly the shoes cost €400,- and now €181,-
The next days I walked without no problems and blisters, the shoes fit great and walks great and have great traction also in wet conditions.
After 6 days walk in the Alps, normal mountainwalks above 2000 meter sealevel, the sole wears off.
I send a message to the Mammut factory and I must send my shoes to the factory. After two weeks my shoes came back, with new soles and extra laces and inner soles. Normaly the Eiswand GTX have Vibram Maton soles. Now I have Vibram Teton soles under the shoes, the same Mammut use for the Nordwand TL shoes or the Magic Peak High GTX.
In a coupe of weeks I go to the Alps again for mountainwalking and hope the sole is great.
For now 3 stars, maybe 5 as the new sole is great and not wearing off.
For service Mammut got 5 stars.
