Familiarity: I've used it several times
I purchased these recently after skiing in the TLT 5 Mountain for the past 3 seasons. After looking at these boots in a local shop, I knew I had to make the upgrade. I loved the my old TLT 5, but it had a couple of areas in the design that I felt could be improved upon. First, the removable tongues were cumbersome, awkward, and time consuming, especially when transitioning frequently. When in walk mode, the old Ultralock buckle was bulky and made it impossible to use gaiters. This may seem like a minor point, but it nearly caused me to fall because my crampons snagged my pant legs while traversing a steep section on Mt. Hood. The buckle also eventually wore a hole in the inner cuff of my $400 ski pants. The standard velcro Powerstrap on the old model never stayed where it was supposed to while hiking. The lace system of the boot liner never stayed tied, and eventually the eyelets broke forcing me to abandon the laces entirely. The new TLT 7 addresses all of these issues while maintaining the same great characteristics on both the up and the down. The tongue is now fixed to the boot, eliminating the need to play with cold, icy plastic parts while on top of a windy ridge. The Ultralock 3.0 system uses a sort of double-throw buckle system that makes the boot much less bulky. It is also much easier open and close the buckle when switching from walk to ski mode. The old velcro Powerstrap has been revised to use a cam buckle closure that significantly stiffens the boot and stays put while in walk mode.
The new velcro closure on the boot liner is an improvement on the old lace system, but this is the one area that I feel could still be improved upon. The only other downside is that for me, the TLT 7 is 4 mm shorter in the sole length than the TLT 5 (in size 27.0), requiring me to remount my fixed-mount Superlite 2 bindings. Remounting could have been avoided if I had been willing to buy the adapter/adjustment plates from Dynafit which seemed overpriced at $85. If you have never tried any of the TLT boots, I can tell you that the 60 degree range of motion in the walk mode makes a huge difference over many other AT boots that only have 30 degrees of range. This translates into much less fatigue, and more vertical feet on your tours. The boot also skis as well as anything other than alpine boots while weighing 4 or 5 pounds less. Overall, I highly recommend these boots to anyone in the market for an AT boot, and in my opinion it is probably worth spending the extra money on the TLT 7 versus buying an older version of the TLT on closeout.
