Dynafit Speedfit Pro Boot Review

Dynafit's TLT5 boot was revolutionary. It brought decent ski-ability to boots barely over 1kg and simplified walk-ski mode transitions. At the time, only the Scarpa F1 (with the bellows) and Garmont Masterlite (that didn't last long), were similar in weight, but well behind in skiability (for the former) and durability and simplicity (for the latter). They were light enough that I used them as 1 boot quiver for 1 year as they were as light as the F1 Race they replaced and were able to drive bigger skis like a 95mm x 187cm Dynafit Manaslu.

The design was refined slightly with the TLT6, losing the miniscule forefoot flex that didn't do much and better buckles. I skied the  TLT6 from 2014 until 2020. The liners were getting worn, and buckle hardware loose, so I looked for a replacement.

As with the skis, there were lots of options of boots around 1kg in 2020, but again, the unfavourable exchange rate made the boots seem much more expensive than I remember from 2014. And at the time, Dynafit was experimenting with boots without toe welts with the Dynafit TLT7 and TLT8. I don't use crampons very often, but it would be nice to not have to buy new hardware on top of having to buy new boots. 

Fortunately as part of their budget Speedfit line, Dynafit sold a slightly modified TLT6 in 2020 branded as "Speedfit", with both composite (fiberglass instead of carbon on my TLT6) and plastic cuff versions. Like the Ski Trab Stelvio skis, the Speedfit Pro boot brings the performance of carbon...er fiberglass at a lower price. Combined with the Stelvio skis and the Dynafit Speed Turn bindings, they make a great high performance budget setup.

There are a few notable differences between my Speedfit Pros and my TLT6. My TLT6 had the thicker liners and the lighter weight and less cuff restriction of the Speedfit liners is noticeable on the way up. The Speedfits on the other hand, lose the capability of installing a plastic tongue to stiffen up the boots for the way down. I only really used this feature of the TLT6 during infrequent ski resort days or when touring on bigger skis like. But that brings me to another knock on the Speedfits. The cuff feels less stiff, so I definitely miss being able to stiffen them up with the tongues during the rare times I feel like I need to (last lap of the day?). Fortunately, the Speedfits feature an awesome powerstrap. I never bothered with the velcro powerstraps on the TLT5 and 6, leaving them undone. My TLT5 strap didn't like being loose under my pant cuff and actually ripped itself out of the eyelets. The powerstrap on the Speedfits is a cam lock design that can be tightened by pulling on the tail of the strap (once fed through the cam) and loosened for the next climb with a pull loop. I definitely don't use the powerstrap for short laps, but it doesn't slow things down at the transition area that much for bigger laps.

So you have thinner liners, and can't install tongues to stiffen them up, and the cuff isn't as stiff to begin with, but the powerstraps are much better to use so they have that going for them. Aside from the uphill performance, which is a little bit better due to the lighter weight. Again, a decent budget boot that probably skis better than the plastic boots in the same price range.
