Das sagen Bergfreunde aus aller Welt dazu:
I bought a pair of La Sportiva Trango Tower GTX and after 6 month of use, I needed to resole them.
Attached you have photos. You can make yourself a picture. Within 20 hikes the tip of the sole was worn completely off. What is written nowhere is that this boots have a very technical and soft compound sole. This sole will grip very good, but it wore off extremely fast. My tips are gone after 6 month of normal use. If you intend to use them for Hiking or trekking, be prepared to resole them within short, therefore factor in, into your purchase price, also a new soles.
I wrote directly to La Sportiva, instead going to my retailer and claim my warranty, as I thought we will find a solution and who better than the manufacturer knows its products, however La Sportiva sees this differently and shown usage is normal wear and tear ( as these are very technical Boots, designed to super grip). I have had better experiences with other Brands. Instead of solving my problem, they sold me a new sole.
Resuming: I bought a new pair of top end boots (not cheap) which did not last 6 month, I need to resole them and pay for the refitting myself. If I would have known before that the Trango will wore off faster than a pair of cheap Trail running shoes , I would never have bought them, not even in sale. The Warranty department was well educated, but absolutely frustrating and not helpful.
After this disappointing experience I do not think that I will buy another product from La Sportiva again. If you like the boots as I did, just be aware and warned that they will not last the first season! But they look very cool.
