The shoes are comfortable, have a soft and well-gripping sole, but unfortunately, they are not suitable for more difficult terrain and do not withstand even light off-road conditions. The leather of the shoe is very soft and started to tear by the sole from the first day of use, and the insoles (foil-backed material at the bottom) completely disintegrated after two days. The leather on the tongue did not even withstand the pull from the laces. I thought these would be good quality shoes, but unfortunately, I have to look for others.

Prabos Grizzly GTX Boots - Brown
High, brown tactical boots made from natural leather, featuring three types of Gore-Tex membrane. They provide thermal comfort at extremely low temperatures down to -50 degrees Celsius. Designed for continuous use in demanding conditions.
three types of Gore-Tex membrane, Three-layer sole
The use of three types of Gore-Tex membrane in the footwear ensures proper breathability and water resistance. The upper leather, subjected to appropriate treatment, is easy to clean and effectively protects against moisture.
Types of Gore-Tex membrane:
- Duracom CC Sportive – thick layer insulating the upper, allowing breathability,
- Duracom MS Sportive – thin insulating layer, provides better tongue support and perfect fit to the leg,
- Thermium – located in the upper part of the footwear, ensuring thermal comfort at extremely low temperatures.
Three-layer sole features high abrasion resistance. The TPU framework stabilises its structure while walking. The polyurethane midsole protects against the cold and offers cushioning. The outer sole has rubber Icetrek studs, preventing slipping.
4-layer CLOUD lining, contoured insole
The two-part insole, suitably contoured, is made of soft PU with a honeycomb structure and PES fabric. 4-layer CLOUD lining enhances cushioning and effectively wicks away moisture. Toe protection is provided by an additional layer of material and the overlapping part of the rubber sole. The upper is connected to the sole via the direct injection moulding process.
The footwear is adapted for basket crampons.

Gore-Tex is a thin membrane made of polytetrafluoroethylene (ePTFE), which features a microporous structure. Its structure makes it highly water- and wind-resistant, as well as breathable. The membrane's pores are 700 times larger than a molecule of water vapor, which allows it to efficiently wick moisture to the outside. Gore-Tex is widely used in the production of outdoor clothing and footwear.
Gore-Tex Duracom CC Sportive is a membrane used in footwear designed for use in cold weather. A thick insulating layer made of non-woven fabric with a grammage of 200 g/m2 is responsible for the slow loss of heat emitted by the foot, providing protection against the cold. High waterproofness protects against moisture and wind, while vapor permeability allows excess moisture to escape to the outside.
Gore-Tex Duracom MS Sportive is a membrane with a thin insulation layer used in footwear designed for activities in moderate to warm conditions. It features high water resistance, breathability and efficient vapor transmission. It represents a compromise between high vapor-permeability and moderate thermal insulation.
Gore-Tex Thermium is a waterproof and breathable membrane with an innovative ultra-thin insulating layer - mainly used in winter footwear. The insulation, based on a combination of PTFE and silica areogel (a thermal insulator), is characterized by low water absorption. As a result, it retains its high insulating parameters and performs best at temperatures from -5 to -50 deg. C, protecting the areas most vulnerable to freezing (toes).
Icetrek is a type of soft rubber that retains its elasticity even at very low temperatures. Due to its properties, which provide good traction and grip on cold, icy and snowy surfaces, it is used, among other things, in the manufacture of soles for winter boots.
4ply CLOUD is a type of soft anatomically molded padding in footwear that effectively increases cushioning and efficiently wicks away moisture.

The shoes are warm, but claiming durability down to -50°C is an exaggeration – they do not provide that much warmth. A big downside is the insole – at the front, underneath the toes, it's covered with aluminium foil, which started to crack and crumble after a few outings. Sharp tiny pieces have formed and I'm worried they might damage the membrane.

I bought the shoes at the end of August – they performed well during heatwaves (+30°C), although foot sweating was normal in such conditions. In September, I used them intensively for two weeks on the training ground – I developed some minor blisters on my heel and the outer part of my big toe. Then, I wore them at the unit in mid-October and during a week on the training ground in the rain. In November, they were used again on the training ground in mud and rain. Now, with snow falling and temperatures below zero, I no longer feel the features of these shoes previously mentioned. The shoes start letting in moisture after 4–6 hours of service. At -14°C I almost suffered first-degree frostbite. Their main advantage is the sole – it really protects against injuries (slipping, twisting) – and the self-sealing upper (several times I stepped into mud or water up to about 18 cm and they did not get soaked). After walking about 800 km in them in 3 months, I think the price of over 1100 PLN is inflated – personally, I'd pay a maximum of 600 PLN. If they weren't so heavily advertised and had an adequate price, I'd probably buy them. Unfortunately, due to numerous exaggerations and information in the description not matching reality, I do not recommend these boots, and in my opinion, a rating of 2 is appropriate. Regards.

These shoes should cost a maximum of 700 PLN as of December 2023. After 6 hours of service at -3°C, dampness started to appear, and after 13 hours at -14°C my toes were blue. After just 10 minutes without movement, the whole foot was frozen – only during constant walking do the shoes keep warm (I was wearing two pairs of Merino socks). The strong point is the sole – it insulates well from the ground and prevents slipping, which saved my joints several times. Additionally, the foot is securely placed in the shoe, but at this price that should be standard. My maximum rating is 2 stars.

I bought these shoes and I'm satisfied with them – they are light and warm. The only issue I had was sizing, because with a foot length of 28.5 cm, size 43 turned out to be too small, so I exchanged them for 44. I think they are better than the ones I had in England.

The shoes are very comfortable and warm. After walking several kilometres, I can already say they are worth their price.

They perform excellently in the field. They don't let water in and your feet stay dry. The only downside is the price, but you have to pay for high quality.
