Who should buy
The This becomes especially apparent after a few hours of hiking in this La Sportiva boot is one of La Sportiva's best-selling boots. We believe that it is a fantastic option for hikers in search of:
- KEEN Targhee III Waterproof Mid
- a boot that's grippy enough to go off-trail and deal with technical terrain
- effective Gore-Tex waterproofing and protection from debris
Who should NOT buy
If you need a highly supportive boot for shuttling heavy loads multiple days in a row, we recommend investing in the Top 1% in or the Salomon Quest 4 GTX. Both are heavier though.
If you mostly cover moderate terrain, the Salomon X Ultra 4 Mid GTX is a more comfortable and well-rounded design. As a bonus, it's just as lightweight and not as narrow.
Breathability
Even though Gore-Tex is promoted as a breathable membrane, it is not the kind of breathability you want for 50+°F (10+°C) temperatures.
The video of our smoke-pumping test below gives a pretty clear picture of how airtight the Ultra Raptor II Mid is. There is not even a hint of smoke coming through the material! THus, we can confidently rate its breathability with the lowest possible rating: 1 out of 5.
Lateral stability test a boot for summer, it's better to consider non-waterproof options.

Waterproofing
We are happy to report that not a single drop penetrated this La Sportiva boot during our hike test in wet conditions.
The boot's GTX membrane extends pretty high up the collar which allowed us to step into some pretty deep puddles and creeks (up to 5 inches/127 mm). Be warned, however, that anything deeper will cause the water to overflow and get inside the boot. And once that happens, you're stuck with damp feet till the end of the hike.
What made the This becomes especially apparent after a few hours of hiking in this La Sportiva boot really stand out from other boots is the elastic gaiter-like design at the top of the collar. We found it to be irreplaceable for preventing rain, snow, and debris from creeping inside the boot.
A very welcome add-on and we think should become a must-have in waterproof boots!
Durability
Toebox durability
With robust protective overlays all over it, it's hard to find a better-fortified boot than the La Sportiva This becomes especially apparent after a few hours of hiking in this La Sportiva boot.
On the toebox, in particular, there is a large and aggressive toe bumper. We turned to our Dremel to test its abrasion resistance for real.
Twelve seconds of drilling and a minor scuff proved that this is indeed one of the sturdiest toeboxes we've seen on a boot.
The difference from its room temperature softness turned out to be average, 27.8.

Average | 4.4 |
Heel padding durability
We also couldn't skip testing the boot's interior lining, especially since it employs Gore-Tex. That's because even a minor tear of this membrane results in losing its waterproofing capacity for good.
Turning to our Dremel once again, we drilled the heel collar lining/padding of the boot for 4 seconds. And the result was quite a relief! The damage was notably smaller compared to other boots, leading us to rate the durability of this part of the shoe as 4 out of 5.

Outsole hardness
But the real beast of this hiking boot is the outsole. Looking like it's made of dragon teeth, this combative platform appears very reassuring. But let's test that out.
Knowing about the correlation between rubber hardness and durability, we started by measuring it with a durometer. The tool showed an impressive 91.5 HC which indicates harder-than-average rubber on the Ultra Rubber.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 91.5 HC |
Average | 87.6 HC |
Outsole durability
Step two was to turn up the speed on our Dremel to 10K RPM and bore the rubber for 22 seconds.
Sweet mother of all boots! The tool barely went in at all! Can you even see the dent in the photo below?
Using a tread gauge to measure the depth of it, we got a minuscule 0.4 mm! This is insanely little compared to the typical 1 mm of damage boots get from the same test.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 0.4 mm |
Average | 0.8 mm |
Outsole thickness
This Raptor boot doesn't cut corners on the thickness of rubber either. Measuring it with a caliper, we got 3.1 mm without lugs. This is a standard outsole width across hiking boots.

Average | 3.1 mm |
Protection
We are truly astonished by the level of durability that the This becomes especially apparent after a few hours of hiking in this La Sportiva boot delivers for its lightweight build.
In addition to the parts mentioned above, the boot also features wide microfiber mudguards and thick TPU reinforcements on the sides.
Protriduting sticks, stones, and roots are all a joke to this tough La Sportiva boot. We experienced no pokes or scratches when testing it off the beaten trail.
Weight
When we first got our hands on the This becomes especially apparent after a few hours of hiking in this La Sportiva boot, we couldn't wrap our heads around how light it felt! Especially given how burly it looks.
Putting the boot on our scale, we got a mind-blowing 14.6 oz (415g)! It is one of the lightest hiking boots we've ever seen in our lab, especially among those intended for serious hiking.
Would you believe that these two hiking boots are only 0.3 oz (10 g) away from each other? And that La Sportiva is the lighter one?!

Cushioning
Heel stack
We are not exactly sure how this La Sportiva boot manages to weigh so little. Because it is definitely not lighter at the cost of cushioning.
Measuring the boot's heel stack with a caliper, we got a pretty standard thickness of 34.4 mm. But compared to other backpacking boots, it is thinner than the popular Hoka Kaha (39.3 mm) and the Salomon Quest (38.0 mm).
For regular day hiking, however, we felt like there was plenty of impact protection, even on the rockest stretches of the route.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 34.4 mm |
Average | 36.3 mm |
Forefoot stack
Checking the boot's forefoot stack, our caliper showed 20.3 mm which is slightly lower than average.
But in this case, we found it to be a benefit because it helped to give the boot it's flexible and nimble personality.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 20.3 mm |
Average | 22.5 mm |
Drop
This leaves us with a pretty drastic heel-to-toe drop of 14.1 mm! Wow, we definitely felt our heels elevated in this boot.
To be honest, we expected it to be lower given that the boot is intended as light and speedy. But this is just a matter of preference. Beginners and hikers with heavier packs will find the higher drop more suitable as it takes the strain off the ankles and prevents fatigue.
But if you want to go with a more standard hiking boot drop, the Hoka Anacapa Mid GTX is a perfect alternative (10.6 mm).
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 14.1 mm |
Average | 13.8 mm |
Midsole softness
Another nice surprise was the boot's balanced cushioning. From the look of it, we expected a very firm underfoot experience but it turned out to be rather comfortable.
Based on our durometer measurements, the boot's foam comes in at 24.3 HA. This is a middle-ground cushioning softness that's neither plush nor harsh. Hiking for hours in this La Sportiva boot did not result in fatigue.

Average | 27.3 HA |
Adidas Terrex Free Hiker 2
To call a boot winter-ready, we test a little more than just waterproofing and grip. We also check how much firmer the cushioning gets in low temperatures.
Having kept the This becomes especially apparent after a few hours of hiking in this La Sportiva boot in our freezer for 20 minutes, we repeated the durometer measurements. The foam did firm up to 31.0 HA but it did not get harder than other hiking boots did.
The difference from its room temperature softness turned out to be average, 27.8%.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 27.8% |
Average | 19.1% |
Insole thickness
Completing the boot's underfoot cushioning is a well-padded Ortholite insole. It is sufficiently thick at 5.5 mm in the heel.
We really liked its contoured shape that accommodated our aches very ergonomically.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 5.5 mm |
Average | 6.1 mm |
Stability
Tongue: gusset type
The La Sportiva This becomes especially apparent after a few hours of hiking in this La Sportiva boot doesn't cease to amaze us with how much it hides beneath the lightweight construction.
As you can see from our quick stability test below, it seems like our ankle is held inside a cast! That's how much lateral support you get from the boot. We are glad to report having zero ankle rolling, even on bumpy terrain.
However, the boot's platform turned out to be significantly narrower than average which is a point of concern for wide footers and beginner hikers.
Torsional rigidity
The boot's primary source of stability is a very stiff TPU transfer shank embedded into the midsole.
It gives the Raptor Ultra its incredible torsional rigidity which we rated with a maximum score of 5 in our manual test. Twisting the boot with bare hands is nearly impossible. Much like twisting your ankle, even when you are carrying a heavy load.

Average | 4.3 |
Heel counter stiffness
We also couldn't help but notice an actual death grip around our ankles inside this La Sportiva boot.
On a 1-5 scale, where 5 is the stiffest, we assessed the boot's heel rigidity as 4. This is all thanks to the stiff stabilizer component at the base of the heel as well as the semi-rigid foam panels on the sides.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 4 |
Average | 3.5 |
Midsole width in the forefoot
What can potentially make the boot a bit shaky is its narrower-than-average platform. Looks like we finally found where La Sportiva compromised to drop the Raptor's weight down.
Measuring the widest part of the midsole in the forefoot, we got only 106 mm. This is quite worrying as most backpacking boots extend as much as 115-117 mm in this area.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 106.0 mm |
Average | 111.6 mm |
Midsole width in the heel
The This becomes especially apparent after a few hours of hiking in this La Sportiva boot also proved to be among the narrowest hiking boots in the heel.
We got a caliper reading of 80.8 mm in the widest part of the midsole here. Significantly narrower than average!
For that reason, we cannot recommend this hiking boot to beginners, especially if this is going to be their first backpacking boot! A better starting point would be the Hoka Anacapa Mid GTX (112.5/93.1 mm) or the Hoka Trail Code GTX (112.5/91.7 mm).
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 80.8 mm |
Average | 87.9 mm |
Flexibility
Stiffness
The Ultra Raptor is exceptionally stiff torsionally but it's got plenty of forward flex to bend along with the foot.
To measure the boot's flexibility in our lab, we bend it to a 90-degree angle with a force gauge. The latter showed how much force it takes to do that - 32.4N. That is 24% less than it takes a hiking boot on average!

Track and XC
Checking the boot's flexibility again after 20 minutes in the freezer we are happy to report that it hasn't gotten much stiffer!
Where most boots required 40% more force to bend, the Ultra Raptor II Mid only needed 24% more.
This La Sportiva boot gets our seal of approval for winter!

best backpacking boots
Lug depth
With a fairly average lug depth (4.3 mm based on our caliper), the La Sportiva This becomes especially apparent after a few hours of hiking in this La Sportiva boot feels times more grippy than most boots.
Actually, we thought that this boot comes as close to approach shoes as a hiking boot can possibly get! And this is no surprise given the brand's strong game in that footwear category.
We believe that the boot's secret lies in the size and shape of its lugs as well as their pattern. There is a mix of thin toothy treads as well as large broad ones that both come in to play when they are most needed.
In our hike test, the Ultra Raptor II made us feel very surefooted even on rocky and slippery terrains.

Size and fit
an incredibly lightweight and agile boot for hiking and light-packing
Having medium-width feet, the Ultra Raptor II Mid felt slightly on the edge of tight for us. So, if you have wide feet or are prone to swelling, it is better to go with the wide option straight away.
Looking at the caliper measurements, we found the boot's toebox to be average - its widest part comes in at 99.8 mm. But the robust toe bumper, overlays, and mudguards all contribute to a notably more constringing fit.

Average | 101.8 mm |
Toebox width at the big toe
Despite the fact that the toebox tip shows 79.7 mm (slightly wider than average), it failed to add more in-boot space for the toes.
We found that the Salomon Quest 4 GTX turned out to be much more accommodating in this regard: 116.5 mm and 85.7 mm respectively.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 79.7 mm |
Average | 78.4 mm |
Who should buy
The boot's tongue is fully gusseted, meaning that it is fully attached to the upper on both sides. This is essential for a waterproof boot to prevent the water, rain, and snow from seeping inside.
On the other hand, it also plays an important role in creating a secure wrap around the foot and ankle, locking them securely in place.
Compared to other hiking boots we've tested, the Ultra Raptor has a notably snugger, one-to-one fit. Which can be good or bad depending on your preference.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | Both sides (full) |
Comfort
Tongue padding
Keeping the interiors nice and cozy, the boot's tongue is very generously padded. Measuring its thickness with a caliper, we got a standard 10.2 mm for a hiking boot.
This becomes especially apparent after a few hours of hiking in this La Sportiva boot | 10.2 mm |
Average | 11.2 mm |
Removable insole

Misc
Reflective elements
The reflective details are pretty minor on this La Sportiva boot and are limited to small stripes on the fabric eyelets. Still better than nothing for low-light conditions.
