Fit: Fit is very subjective, however we can note a few things, same fit as TLT7 (which is noticably wider and higher volume than the TLT6). This therefore is the widest available touring boot on the market with a stated last of 103.5. It is extremely comfortable for my feet, i drive, get groceries, and pretty much do anything with it unimpeded. Another fitment note is that Scarpa has primarily gone to carbon infused grilamid which they say you shouldnt punch (side note: you can, but it voids warranty and is very hard to do). Atomic uses memory fit which bakes the entire shell, but also requires special equipment and makes the plastic less responsive to pinpoint punching. What this means is that if you have ugly feet with bunions and bulges, this is one of the few remaining boots that is extremely easy for bootfitters to work with, and amateurs like myself to punch in my garage without specialty equipment. If you have a typical "north american foot" ie generally wider forefoot with a medium to narrow heel, then you may like this boot. It doesnt require you to have pointed ballerina feet like all the other lightweight 2 buckle boots (and it skis better, though obviously whatever fits you best will ski best, but this is the stiffest option).
Stuff that they need to fix but isnt a deal breaker: user serviceable upper cuff pivot joint. For some reason dynafit has been dragging their heels on a user servicable cuff joint. For biking nerds out there, the system they use is reminiscent of a pressfit BB. This means that they press the joint together at a factory. It works, but the more you use the boot, the more play develops in the joint between the upper and lower cuff. It also creates a slight amount of friction. Other manufacturers, like atomic, utilize a frictionless pivot that can be retightened at home, instead of having to be sent back to dynafit and repressed. The other option is to buy the B&D Ski gear ultimate cuff pivot, drill out the pressfit pivot, and install (not too terrible, ive done it on the Dynafit PDG 2). And drilling your boot will void warranty. This is a very easy fix for dynafit, specifically because they partner with Pierre Gignoux which uses a user servicable cuff on all boots, so Dynafit does know how to do it properly.
Secondly, as their premiere light and fast but still skis great boot, i find it odd that the transition now is longer than their beefier boot, the Hoji (excellent boot). The hoji utilizes a single throw rear latch which tightens the upper cuff, the booster strap, and locks the cuff. Similarly, dynafits premier race boot, the DNA (rebranded Pierre Gignoux Race 400) also tightens the upper cuff and locks it with a single throw of a latch. The TLT8 requires you to throw a side latch which locks and tightens the upper cuff, but you have to tighten to booster strap separately. You can remove the strap but it improves skiability. (Side note: the booster strap is far superior to those like on the Scarpa F1, it utilizes a camlock rather than velcro which should prove more durable and is easier to adjust.) So the next iteration imo should either adopt a version like the Hojis or like the DNA.
Summary/whose it for: light and fast users who want a strong boot for the downhill and want to not notice what's on their feet on the up. Comparatively i find it has the strongest ski performance in the weight class, and accommodates wider feet the best of any boot off the shelf. Dynafit also has an excellent warranty service.
*final note: the dynafit tlt 7/8 and hoji all utilize the speednose which is a unique design that eliminated the front welt. This serves several purposes, it allows shorter bsls, it provides a more natural pivot point (pins under toes rather than in front of them) which reduces fatigue and makes a more natural stride) and lastly if you climb ice in ski boots like i do, it allows for higher performance by allow the frontpoints to be closer to the boot rather than protruding far in front. This has the same effect of reducing the overall lever of your ankle and foot, thereby alleviating calf strain and allowing more precise placements. Ive climbed about 30 days of ice in Hojis (the same toe) and find the tech to work, both providing a more secure fit and compatible with any semi automatic toe piece on the market. I put a semi auto toe piece on my grivel g20s and havent thought about it sense. Some folks complain about this innovation, but they are probably unaware that a properly fitted semi auto crampon is both more secure than a fully automatic, and allows again for closer frontpoints for improved performance . To the haters who refuse to buy the boot because theyve been misled that you can only climb ice with full autos, i suggest breaking out of your shell and getting with the times, you wont miss it! After leading my ice block, i in fact watched my partners full auto crampon sheer sideways off of his boot while leading. You cant experience that with a semi auto! It's safer!
I have not submitted this as an official review yet because i do not believe in giving full reviews after only a month. I intend on releasing a full review at the end of the season. Thanks, and if you have questions let me know! Dynafit #speedup
