About
What it is.
Nucleo High II GTX is a mid-height hiking boot from La Sportiva's backpacking line, built around a nubuck leather upper and Gore-Tex Surround construction. This membrane setup wraps the boot to manage moisture from both outside and underfoot, aiming to pair weatherproofing with a level of airflow not typical of waterproof boots.
It's positioned for hikers and backpackers covering mixed, unpredictable terrain who need footwear that holds up mile after mile without letting them down. Within La Sportiva's footwear range, it sits as a mid-duty option, built for those wanting dependable trail performance without stepping up to heavier mountaineering boots.
The verdict
The Nucleo High II GTX ranks fifth for winter hiking boots, with buyers consistently praising its immediate comfort and fit across varied terrain, but durability remains a weak point—some owners log months of daily wear while others face premature sole and upper failures. At $239–$259, it delivers genuine comfort for moderate use, though marketing overstates its durability claims.

Who reviewers think this product is — and isn’t — for
For you if
Look elsewhere if
You need boots you can trust on varied terrain without worrying about failure.
La Sportiva is an established brand, 202 reviews show broad consensus, and the product is mature; low durability marks prevent a higher score but don't undermine proven reliability.
You want solid hiking boots that won't break the bank but deliver real performance.
Mid-range price with strong 4.0 rating and proven comfort/traction covers the essentials well; cheaper rivals exist but this balances cost and capability honestly.
You want hiking boots that work straight out of the box without fussing.
Insulated waterproof boots are straightforward to use, but high comfort/fit marks suggest they may need break-in or adjustment rather than pure plug-and-play simplicity.
You seek prestige and flagship design from an established maker.
La Sportiva carries brand prestige, but the Nucleo High II GTX is a solid workhorse rather than a flagship statement piece; positioning is utilitarian, not premium. Consider Renegade GTX Mid.
You demand the absolute best in every measurable way.
Strong comfort and traction ratings are offset by low durability marks and mid waterproofing; not top-of-class across the board, and marketing honesty is weak. Consider Renegade GTX Mid.

Frequently asked
What buyers want to know.
Is the La Sportiva Nucleo High II GTX waterproof?
Reviewers say the waterproofing performs reliably in creeks, snow, and wet conditions. It handles mixed three-season trail use well.
Does it run true to size?
The boot runs narrow and needs a break-in period to soften up. A wide version is available for those who need it.
Who is this boot best for?
It suits hikers and backpackers who want a lighter, flexible boot with solid waterproofing and grip for mixed three-season trail use. It is not suited for hikers needing maximum ankle rigidity for heavy packs or anyone hiking regularly in hot weather.
How does the grip and support compare to heavier backpacking boots?

What are the main drawbacks?
The laces loosen and won't stay tied. It gets hot and sweaty in warmer temperatures. Durability is inconsistent—some owners report months of wear with little damage while others face premature sole and upper failures.
How comfortable is it out of the box?
Reviewers consistently praise its immediate comfort and fit across varied terrain. The leather and mesh upper is flexible and durable, and the ankle collar and toe cap offer good support without excess bulk.
