I have owned my pair of Hi-Tec Men's Altitude Ultra Light Hiking Boot for about two years. I only use them for mountain hiking, so I'd say they have been used less than 100 times (on day hikes). They have never been very comfortable. I bought them because I trail talk using Hi-Tec (regular Altitude($79)) almost daily and I am on my third pair over about a 6 years period (or well over a thousand 3 mile plus walks). They are the best shoe (of any kind) I own period. But back to the Ultra's. After about 50 uses the sole was peeling away from the body and the leather uppers were quiet torn up from the hiking wear and tear (no pun intended). This has made the Ion-mask process (see their video) useless and the boot allow water to penetrate during snow and/or other wet hikes. Bottom line is if they would just but the Vibram sole on the $79 boot, it would out last, outperform, and be most comfortable then this boot for close to half the price.
