Groundies All Terrain High Review - 2.0 Fit & Grip

The short answer

I wore an earlier Groundies All Terrain High for hiking, dog walks and wet-weather everyday use. I liked how light and flexible it felt for a high-cut outdoor boot, and my feet stayed dry during the rain I encountered. I also found two real drawbacks: my pair felt narrower than the marketing suggested, and the outsole could feel slippery when wet.

The product shoppers find today is the All Terrain High 2.0. Groundies now uses a GH2 TrueSense hiking sole, a waterproof/breathable membrane and its current Barefoot Fit. I have not worn the 2.0, so this page keeps my earlier-generation experience separate from the current manufacturer's specifications.

That distinction matters because Google already sends people here for “Groundies All Terrain High 2.0 review”. The useful answer is what I learned from the earlier boot, what Groundies has changed, and what still needs verifying on your own foot.

Current All Terrain High 2.0 specification

Groundies' current All Terrain High 2.0 pages, checked on 23 August 2026, publish:

• Fit: Barefoot Fit, which Groundies places between Barefoot Light and the wider Barefoot+ fit
• Drop: 0 mm
• Upper: recycled-polyester / recycled-plastic-composite mesh
• Weather construction: waterproof, breathable membrane
• Outsole: GH2 TrueSense hiking sole
• Insole: removable, moisture-regulating microfiber construction
• Upper details: ankle padding and stabilising lacing zones
• Manufacturing: designed in Germany, made in Vietnam
• Women’s sizes currently listed: EU 36-43
• Men’s outdoor range currently lists the model through: EU 40-48

Groundies describes the current fit as medium width: roomier than Barefoot Light but narrower than Barefoot+. That is more useful than simply calling the boot “wide-foot friendly”.

How thick is the current sole?

Groundies' own current page gives two descriptions that do not reconcile perfectly. The specification panel says 2 mm base + 3 mm profile, while the feature copy describes the GH2 sole as having a 5.5 mm construction.

Rather than turn that into another false-precision “5 mm stack” claim, I would read it as a very thin hiking sole with roughly 3 mm of tread/profile and ask Groundies if the exact total stack matters to your decision. The old article's blanket “5 mm stack without the insole” should not be treated as the current published measurement.

What I liked about my earlier All Terrain High

Light and flexible for an outdoor boot

The main thing I noticed was how little the boot felt like the conventional hiking footwear I had used before. It was easy to bend, did not feel cumbersome on ordinary walks and worked for me as both a casual boot and a short-hike option.

The current 2.0 still uses Groundies' flexible TrueSense concept, but I have not tested whether it feels identical underfoot.

My pair handled the rain I used it in

On a long wet walk, my feet stayed dry and warm. That is useful first-person evidence for my pair.

The current 2.0 has a manufacturer-specified waterproof, breathable membrane. I would still avoid “100% waterproof forever” language. Membrane performance can depend on wear, seams, contamination and care, and my older pair does not prove how a new 2.0 performs after months of use.

The ankle and lacing were comfortable

I liked the padded higher ankle, reflective laces, lacing zones and heel loop on my pair. The current 2.0 still advertises ankle padding and stabilising lacing zones, so those design priorities have carried forward.

The main caution: wet grip

My earlier All Terrain High could feel slippery when wet. I expected more bite from the tread, particularly on slick surfaces.

This is exactly where a review should not blur generations. Groundies now calls the 2.0's GH2 hiking sole “grippy” and “non-slip”, but I have not tested that revised sole. My criticism applies to the boot I wore; Groundies' current grip language is a manufacturer claim about the 2.0.

If wet-rock or wet-pavement traction is the reason you are buying, I would look for current 2.0-specific independent testing rather than assume either my older experience or the maker's marketing settles the question.

Fit and sizing: do not automatically size up

My earlier pair felt narrow enough that I went up a size, and even then I wanted more room. The old article converted that into “order one size higher”, which is too broad for the current 2.0.

Groundies now labels the 2.0 “runs true to size”, but the same current product page also displays a customer-sizing signal saying most customers choose one size smaller. Those signals conflict.

The safest current approach is therefore to use Groundies' published foot-length and width chart for the exact model. The women's chart, for example, gives both centimetre length ranges and width measurements for EU 36-43.

Also note that the current All Terrain High 2.0 is a medium-width Barefoot Fit, not Groundies' widest Barefoot+ fit. If your main requirement is a genuinely broad forefoot, that distinction matters more than a generic “wide toe box” label.

Is the 2.0 actually different from the boot I wore?

Yes enough that I would not pretend this is a first-person 2.0 test. The current model explicitly uses the GH2 TrueSense hiking sole and Groundies' current Barefoot Fit framework. The product page also gives a different, more structured set of current width and sizing measurements.

What still transfers from my review is the use case and the questions worth asking: how the boot feels over a long walk, whether the width works for your foot, how the membrane performs in real rain and whether the outsole gives you enough confidence on slick ground.

What about the environmental claims?

The current product page gives one concrete fact I am comfortable carrying forward: Groundies lists the upper as made from recycled polyester / recycled plastic composite material.

I would not repeat the old article's broader claim that the manufacturing process is “entirely eco-friendly” or treat a carbon-offset statement as proof of that. Recycled content is a material fact; whole-product environmental impact is a much larger claim.

Care

The old review invented a rigid weekly cleaning and polishing schedule. I would not keep that.

For the current 2.0, follow Groundies' current textile/membrane care instructions for the exact colourway and avoid assuming that more frequent treatment is automatically better. If preserving waterproof performance matters, use a product compatible with synthetic uppers and breathable membranes rather than generic shoe polish.

Who should consider the All Terrain High 2.0?

It is worth comparing if you want:

• a zero-drop outdoor boot with a waterproof/breathable membrane;
• a flexible high-cut boot rather than a stiff conventional hiking boot;
• a medium-width Groundies Barefoot Fit;
• an outdoor outsole with roughly 3 mm of tread/profile rather than a deep conventional hiking lug;
• a boot for hiking, trekking and everyday wet-weather use.

I would compare something else if:

• you need Groundies' widest Barefoot+ fit;
• deep aggressive lugs are a priority;
• you need independently verified wet-surface grip before buying;
• you want a leather rather than synthetic/recycled-textile upper.

Would I buy it today?

I liked my earlier All Terrain High enough that I would consider the 2.0, especially for the same mixed casual/walking use. I would not buy it blindly from my old review, though.

I would first check the current size chart rather than automatically sizing up, and I would want current evidence on wet grip because that was the main weakness of my pair. The 2.0 may improve that with its GH2 sole, but the honest answer is that I have not personally tested the revision.

How this review was checked

This update preserves my first-person experience with the earlier All Terrain High and re-checks the current All Terrain High 2.0 against Groundies' product pages on 23 August 2026. Current manufacturer information confirms the 0 mm drop, medium-width Barefoot Fit, recycled-polyester upper, waterproof/breathable membrane, GH2 TrueSense hiking sole, removable insole, German design and Vietnamese manufacture. It also exposes conflicting current sizing signals, which is why this review now points readers to the exact size chart rather than prescribing a universal size change.
