Tim Nwrote a review of La Sportiva Trango Cube GTX Mountaineering Boot - Men's on November 27, 2018
I bought the boots in August 2018 and used them just once. They were kept on the shell in my garage. By Nov one of the boot's heal started splitting. I contacted Backcountry because the boots were still under warrantee. I was advised to provide evidence which I did. I mailed the pair back and received a new pair. I appreciated Backcountry's service. I strongly believe the new pair will have similar problem. I probably will not file for warrantee again if it happens again. La Sportiva make good 4 season full leather boots. I bought my La Sportiva Napal Cube prior to this pair, used them a lot, and they show no sign of splitting. BTW, my wife's La Sportiva Trango Tower GTX are also showing sign of heal slitting after one moderate use (very much brand new). If you have other choices, please don't waste your money until La Sportiva correct the problem!
