Combat boots have grown in recent years from purely military gear into a popular piece of footwear for daily use — on the street, while hiking, and at festivals. But not every “combat boot” is the same. In this guide we explain what authentic combat boots must meet, how to choose the right size, and how to keep them in good shape for years — so you don't pay for quality that isn't there.

What makes a combat boot a real combat boot?
Not every tough boot is a combat boot. Real military shoes are produced to international quality standards, such as NATO AQAP 2110 and ISO 9001. Among other things, that means:
- Full-grain leather of at least 2.8 mm thickness, without a thin PU coating
- A direct-injected sole construction that withstands long, intensive use
- Consistent quality control per production batch
Models like the M77 are the best-known example: a Norwegian design that has stayed in use through several NATO countries for more than 50 years, precisely because it has stayed simple and solid instead of being constantly “improved”.
1. Material: full-grain leather versus split leather
The upper largely determines how long a combat boot lasts. Full-grain leather is the top, strongest layer of the hide and ages in a beautiful way — this is what you see in military-certified models. Cheaper combat boots often use split leather or a leather/textile mix, which wears faster and is less water-repellent.
2. Certification: look for NATO standards
Combat boots that are actually produced for armies often carry a certification such as NATO AQAP 2110 (quality management system for defense materiel) and ISO 9001. This is not a marketing trick — it means the factory is subject to strict, repeated quality checks. A boot without any certification may look the same, but has not passed that control.

3. Sole construction: direct-injected versus glued
With military quality, the sole is usually molded directly onto the upper (direct-injected), which gives a seamless, watertight bond that doesn't come loose. With cheaper shoes the sole is often glued, which can come loose over time — especially with moisture and intensive use.
4. Which size combat boots should you order?
Most military combat boots are designed to be worn with thick or double socks — a practical requirement from the army for use in cold or wet conditions. That means that with most models you should order half to a full size smaller than you are used to. A few rules of thumb:
- Torn between two sizes? Choose the smaller one.
- Will you wear the boots with thick winter socks? Take that into account when trying them on.
- Different models (M77, Aviator, hiking boots) can fit slightly differently — check the specific size advice per model on the product page.
Note: with traditional combat boots the size is sometimes given in millimeters instead of the usual EU shoe size. With Samelin models you don't have to convert that yourself — we simply show the familiar EU size, with the rule of thumb above.

5. Care: this is how your combat boots stay good for years
Combat boots made of full-grain leather are water-repellent, not waterproof. With the right care they do last for years: treat new boots before first use with colorless leather grease, clean them with a brush and damp cloth, and never dry them next to a direct heat source.

6. Warranty and country of production
Where a boot is made says a lot about the quality control behind it. European production (for example Estonia, where brands like Samelin have made boots for several NATO armies for 75+ years) usually means stricter labor and quality standards than mass production elsewhere. Also pay attention to the warranty period: a 2-year factory warranty is a good sign that the manufacturer has confidence in its own product.
In summary: the checklist for buying combat boots
- Full-grain leather instead of split leather or faux leather
- NATO AQAP 2110 and/or ISO 9001 certification
- Direct-injected sole construction
- Clear size advice (often one size smaller than your sneakers) — see our size guide
- Return and warranty policy of at least 2 years
