Protective performance to the core.

The La Sportiva Men's Core High GTX Boot uses Gore-Tex Surround technology to enhance waterproofing and breathability for backpackers and hikers. Unlike traditional waterproof membranes, the Surround membrane wraps completely around the foot for waterproof protection, and it ensures excellent breathability through the sole's breathable mesh inserts. La Sportiva's Nano-Cell upper fuses ventilated AirMesh with protective PU reinforcements for comfort and long-lasting durability.

Underfoot, La Sportiva worked with Vibram to give the Core High GTX Boot's sole plenty of traction on any terrain. The Impact Brake System places slanted lugs at the heel to increase braking power and decrease impact forces by 20%. A compression-molded EVA midsole gives you plenty of cush for long trails, and the TPU inserts ensure stability on rugged ground.

Uber comfortable

  • Fit: True to size
  • Size Bought: 12 / 46

Incredibly comfortable right out of the box. Doesn't feel like there's going to be any break-in period. Feels like your favorite sneaker on foot. Can't comment on durability yet as I just got them but I have no reason to believe it would be an issue. Lateral stability feels good and just the right stiffness in the sole for this type of boot.

Some of the best

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: 43

I'm writing this review because I have read a couple that say these light hikers do not grip. I received my first pair a year-and-a-half ago for my birthday. It was during camping season here in Montana and I put over 300 miles on them right out of the box with no problems at all. Followed by hunting season I put another hundred fifty miles on them with no problems at all. In addition to that I wear them almost every day for daily use, and I've probably put a total of seven to eight hundred miles on my first pair. They still are functional, there's some wear on the outside that looks pretty ratty but nothing leaks they are still water tight. They are the most comfortable, lightest, best boots I believe I've ever owned. I live about 30 minutes away from the Continental Divide Trail so you can imagine what my hiking is like, it can get pretty Extreme at some points especially during late-season elk hunts. The only problem I've ever had with them as that when I first started wearing them around the house they kept grabbing the carpet.
Really one of the most comfortable, and versatile hiking shoes I've ever owned I will never stop wearing them I hope they never stop making them.

Core High GTX for Guiding

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 44.5

I've used this model for guiding backpacking trips and day hikes in Yosemite over the past year. The boots get used nearly five days a week so they have certainly been through the wringer.
A very lightweight and comfortable boot, they take no time to break-in and as long as you're sized right I doubt you can get blisters from these guys. That being said, without a firm sole, you'll feel every rock underneath your feet. So if you prefer a stiffer boot you may want to look somewhere else.
The tread has great traction (almost too great at first) and hasn't worn down much on either pair that I've had.
My biggest complaint is that within a few weeks of owning my first pair a small seam on one of the boots blew out. The seam didn't compromise the structure of the boot at all, but definitely compromised the water-proofing of the boot (which is marginal in the first place.) The boot breaths pretty well and dries out quickly, especially in California's dry heat. So if you're looking for an ultra waterproof boot maybe look somewhere else.
Eventually a hole developed near the toe of one of my boots and I had to retire my first pair. Ultimately they held up better than most boots do in my line of work and performed amazingly the whole time. And so far the seams on my second pair are in-tact.
One other note is that La Sportiva should add a loop at the top of the heel to make the boots easier to put on.
The comfort and flexibility of this boot make it similar to a trail-runner, with extra support from the higher heel. If you're looking for a lightweight, comfortable, breathable boot with some additional support the Core High is a great option.

Grippy boots

Great lightweight hiker. I did have trouble sizing. They do have a fairly wide toe box as I was told. I sized up .5 size as i usually do with LaSportiva, but it was too big. So try on if you can.
Traction, Their sticky rubber and Impact Brake system do work. in my running hoes and the core, i think they are great. Sure you can slip on many things in various situations, but these grip better then most.

Breathes well, not a fan on the insoles

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: 43.5

I have done a few little hikes on these so far including some loose rocky trails, and sandy slot canyons. The first thing I noticed was the insole presses against my heel funny and caused a hot spot after 5-6 miles. I swapped out for some superfeet carbon insoles and have done a few more hikes and that seems to be better for me. So far they breath well and stay dry which is what my sweaty feet needed. Spending a week in Bryce with the new insoles so I will update my review after that. I listened to everyone and went a half size bigger and they fit great.

Great boot thus far

I purchased this boot online from Backcountry (I live in South Florida, so there is not that much choice of hiking boots in the local sports stores). I had to return the original pair as this boot seems to run small, probably more than one size. I purchased this boot for my trekking trip to Nepal in October, and I wanted to make sure I had sufficient time to break it in. However, it appears this boot does not require a breaking in period as it was super comfortable from the first time I wore it. It is extremely light and breathable, and it provides ample ankle support and stability as opposed to the Salomon trail runners that I purchased for a hike in the Swiss Alps last year. Thus far, I am very impressed with the boot. I was able to pick it up at a discounted price of $136.00, but even at $ 200.00, I would consider this to be a good value.

Super comfortable, already leaking.

I love the comfort of this boot. I have day hiked in these about 50 miles total. I have hiked in the cold and snowy to the middle of summer and never really been uncomfortable. They are warm-ish in the winter and cool-ish in the summer. The boots look great as well. The traction is awesome. I live in the Pacific Northwest and these grip great, even when wet.
They run about a half size small. I normally wear 12US and needed a 12.5US in these. They are not real protective. The outer shell while durable does not offer much more protection than a thick sneaker against rocks or roots on the sides of your foot. Being in the Pacific Northwest, it is wet here a lot. Lots of water on the ground. These boots have started to leak a bit around the toes and bottom of the foot. Not sloshing around or anything but still leaking.

This is a GoreTex boot, and I bought them because of that, but they are leaking which is not cool. I have not trashed them at all. I would say I have barely rubbed the initial texture off the treads so they are not that old. Probably another 500+ miles on the tread.

Good thing about GoreTex though is that if they leak they warranty them.

Excellent Boots -

I used these boots on the Tour du Mont Blanc trek and came away extremely impressed with these boots. I used the boots on rainy days in slippery ascents / descents and the grip was tenacious. Feet remained dry throughout rain & streams, while the breathability was phenomenal. I never once felt my feet were overheating, even on very hot days. I highly recommend these boots.

Watch out

Really I don't know if it's only me, but I got this shoes in and is comfortable, good looking and supportive (30 lbs pack) but it has an issue, I took my shoes to a local outdoors store so I could climb a rock ( fake) to simulate hiking, the rock it's only 3 feet high with a good incline, this shoes slid like I was on skates, so they had a pair of La sportiva Syntesis ( low version of this shoes) just as bad, what's up with that? What is the break thing do anyway? If I was out on a trail and hit a wet rock? On my ass I would go for sure, La sportiva you disappointed me. So I say, do your research before you buy it, or you may find your self on your ass with a 30lb pack

In the past I used La Sportiva Trail shoes without a problem, except for their sizing which is all over the place. I have gone from a 41.5 to 42.5 depending on the model. What is their Problem?
Thanks for your honest review, I will stay away from these.

Who writes a review based on trying the boots out on a 3 foot fake rock at a competitors store. I'm on my second pair of La Sportiva hiking boots (not this model) with many miles hiked. I have found their grip very good.

What in the world are you talking about. You walked on a rock in a store. I have had 4 pairs of these and 12 pairs of the Bushidos, they are Absolutely AMAZING>.... Sizing is like a 1/2 size off from US sizing that is my only qualm.
