Field test and first impressions
I have worn every generation of the SNOWGUM Cooper boots since reviewing the Mk2 in 2016 and the Mk3 in 2018. Each version has built upon the previous design, and the Cooper line has earned a reputation for being one of the most reliable and best value hiking boots in Australia. The recently released Cooper Waterproof Boot Mk4 continues that evolution with several practical upgrades that make it the most refined version yet.
The Mk4 keeps the same formula that’s made the Cooper line reliable for me: affordable, comfortable and versatile enough for day walkers, new hikers, youth groups and anyone wanting dependable performance without needing a premium price tag.
What’s new in the Mk4
SNOWGUM has made a handful of practical changes for the Mk4, all aimed at improving fit, comfort and usability rather than reinventing the boot. The footbed is now firmer and better structured, which gives more support through the arch and heel and makes a noticeable difference over longer distances. The four upper hooks on each boot make it easier to fine-tune lace tension across the boot, and while they don’t lock the laces in place the way some premium locking-eyelet systems do, they still give more control than the Mk3 offered. The last is also slightly wider, which suits broader feet or thicker hiking socks and is a noticeable improvement over the Mk3. On top of that, the lace wear and toe rand abrasion that showed up on earlier models have been addressed through stronger components and refinements to the upper. None of these changes is dramatic on its own, but together they noticeably improve the boot’s comfort, stability and fit.
Comfort and performance on the trail
True to the Cooper reputation, the Mk4 feels comfortable the moment you pull it on. There is generous padding around the ankle, a well cushioned tongue and a secure heel hold that prevents slipping. The wider toe box provides more room for natural foot splay and reduces pressure on long days out.
The VaporTEC waterproof membrane continues to perform well. The boots stay dry through wet grass, shallow creek crossings, muddy trails and morning dew. Like any waterproof hiking boot there are realistic limits. The tongue gusset sits roughly 5 cm below the collar, so water deeper than this can enter unless you use gaiters. Waterproofing can be maintained long term with occasional re-treatment using products such as Nikwax.
Breathability is good for a waterproof boot. I experienced minimal heat build-up, even on warm days, thanks to the Cordura mesh panels and moisture wicking lining.
The outsole remains one of the Cooper’s strongest features. Traction is steady and predictable across rock, gravel, leaf litter and damp surfaces. The shock absorbing sole and Phylon midsole help reduce foot fatigue and manage uneven terrain well. The mid-height ankle support offers a balance between stability and freedom of movement.
Build quality and materials
The build starts with the upper: a mix of cow suede leather and Cordura mesh that balances durability against comfort. The suede handles the abrasion in high wear areas where the boot brushes against rock, roots and scrub, while the Cordura mesh keeps weight down and improves airflow, which reduces the heat build-up that often leads to sweaty feet late in the day. Brushed rubber toe and heel guards add impact protection against rocks and help the boot last longer in rough terrain.
The VaporTEC waterproof membrane works on the same principle as membranes like Gore-Tex: the micropores are small enough to stop water droplets entering, yet large enough to allow sweat vapour to escape. This keeps feet dry from both outside water and internal moisture, which matters for preventing blisters on warm and humid Australian trails. Underneath, the Phylon (EVA) midsole is a lightweight foam more commonly used in trail runners, and it provides cushioning and shock absorption without the weight penalty of a polyurethane midsole, which helps reduce foot fatigue over long distances. A plastic shank adds torsional stability underfoot, helping the boot resist twisting on uneven ground and providing extra support when carrying a day pack or lightweight overnight pack.
The last is the same slightly wider fit already mentioned: true to size, with the extra width accommodating thicker hiking socks and broad feet more comfortably than previous models. At 1.1kg, the boot doesn’t feel heavy on the foot, and the durability concerns that existed in older models, such as lace wear and toe rand abrasion, appear to have been resolved in this release. Stitching is clean and consistent and the upper feels strong while still allowing flex.
Care and maintenance
Proper boot care is not only about extending the life of your gear, it is also an important part of responsible hiking and good Leave No Trace practice. Cleaning your boots after every trip helps remove grit that wears down the materials, restores waterproof performance and prevents odours.
More importantly, it reduces the risk of spreading soil-borne diseases such as Phytophthora cinnamomi (Cinnamon Fungus), a destructive pathogen that can be transported in mud trapped in boot treads. Taking a few minutes to clean your boots protects both your investment and Australia’s fragile ecosystems.
According to SNOWGUM, to keep the Mk4 performing well:
- Brush off dirt after each hike. Use a stiff brush for the outsole.
- Wipe the upper with warm soapy water. Do not machine wash under any circumstances.
- Remove the inner soles occasionally to allow the boot to fully air out.
- Dry boots away from heaters or direct heat sources.
- When beading reduces, SNOWGUM recommends using Nikwax Water Repellency Spray to restore waterproof performance.
The Mk4 is the version of the Cooper I’d point people to first. It’s comfortable, stable, durable and waterproof within the limits described above, and the refined footbed, improved lacing and wider last are genuine differences from the Mk3 rather than changes on the box alone. For its price point, it remains one of the best value waterproof boots available in Australia, with an RRP of $179.95 and a Club Price of $99.95. Whether you are new to hiking, gearing up for day walks or simply wanting a dependable boot without the cost of premium brands, the Cooper Mk4 is worth a look.

Product Information
The Mk4 brings together what SNOWGUM has refined across three generations of the Cooper: a firmer, more structured footbed for support through the arch and heel, four tensioning hooks for finer lace control, and a slightly wider last that suits broader feet and thicker socks. The cow suede leather and Cordura mesh upper is paired with the VaporTEC waterproof and breathable membrane, while the Phylon midsole and plastic shank keep the boot light on the foot without giving up support for a day pack or overnight load. The cushioned innersole is removable if you need to fit orthotics. It is a boot built for day walkers, new hikers, youth groups and anyone wanting a dependable all-rounder without paying premium-brand prices.
