I have used this boot for several tours, three races, and countless training sessions and am really starting to love it. I didn't have the chance to try it out before ordering so went off Dynafit's recommendation of sizing 1/2 size smaller than my TLT5 size (28.5) which put me in a 28 for the Evo. When I first put it on, I thought it would never fit and it was way too small - my TLTs were already tight! After putting in a superfeet insert and squishing out the toebox a bit it is now fitting perfectly! With the buckles properly tightened there is no heel slippage except when all out RUNNING. The one handed lock of cuff and switch to ski mode is excellent as with all of the Dynafit boots. The kevlar cord used for the lower buckle strap could be improved. The cord is very slippery and even when tied tightly, comes loose after some time skinning. This can be frustrating and I would rather see a BOA type system. The carbon cuff is attached to the lower boot with a metal rivet. Compared to the rival race boots (Stratos and Alien) that use a bushing, I see this as a bit of a missed opportunity. For a boot in this price range, I wish it had slightly more modern technology holding it together. The liner is comfortable. The plastic snow guard works well in place of a tongue. I wish the sole covered the full bottom of the boot but it does save weight. All in all - this is a ridiculously light boot that has helped improve my skimo racing immensely.
Here is some info on sizing
My boots have been 26.0 and 26.5 scarpa F1
and 26.5 F3.
26.0 for spring and summer 26.5 for winter warmth.
I bought a 28.0 evo( 27.5/28.0 shell)
Took my scarpa/intuition liners from my 26.5 scarpa f3,s and put them in the evo
Even without re-thermoforming they were a perfect fit.
The 27.5/28.0 evo shell is slightly tighter width wise than my F3 26.5/27.0 shells. Lengthwise left good room for my toes.
Evo are small volume shells. An evo 27.5/28.0 shell is very similar to a TLT-5 27.0/27.5 shell. EVO liners are thin.
The boots are a dream for me. Can hike like a light hiking boot or shoe.
I really like this boot. It skis like a TLT6 without the tongue and even less weight. Which says it skis exceptionally well. Sole wear is a problem to be aware of. Still no idea when or if Dynafit is going to offers rubber for a resole. I'd ask first before buying. But as I said...I really like this boot. It is enough boot to push around my 113mm short Huascarans amazingly enough. But better used on lighter, skinnier full on speed touring or race skis.
They fit crampons well (grivel) and climb technical terrian nicely. Just don't use them on rock/talus/ rough trails...the soles will shred in the blink of an eye. 5 star PLUS ski/race boot...3 star skimo boot because of the lack of durability in the sole. Too bad that.
