What exactly are mine resistant boots?

Ukraine’s defense ministry announced on March 22 that the Central Directorate of Material Development and Support, together with the Force Support Command, have begun testing a boot aimed at preventing, or at least mitigating, foot and lower limb injuries for military engineers clearing landmines.

The boots will feature a multi-layer sole made from ballistic materials such as Kevlar, that will help divert the blast and retain the fragmentation from the detonation of an anti-personnel landmine.

In announcing the initiative, Vitaly Polovenko, deputy minister of defense, said: “The main task of such footwear is to preserve the [sapper’s] limb.”

He said: “Our specialists from the Central Administration study various samples of such shoes. They are working on improving tactical and technical characteristics. According to the results of positive tests and the approved reference sample, such mine-resistant footwear will be provided for the Armed Forces of Ukraine (AFU).

Why are the boots considered important?

The scale of landmine defenses laid by Russian forces is so extensive that the threat the AFU deminers face on offensive operations, as well as in clearing liberated territory, has highlighted the need for the best possible personal protective equipment (PPE).

Are these boots a new idea?

The concept of protective footwear for deminers is not new, but – unfortunately – the history associated with this type of PPE is not very encouraging. In fact, the search for a practical and effective solution to the requirement has so far defeated the military and humanitarian demining communities.

The purchase marks a significant shift in Belgrade-Moscow relations, with the former having long relied on the latter for armaments due to the cultural and political ties between the two.

In the January 2023 edition of the UN’s International Mine Action Standards section which covers personal protective equipment (IMAS 10.30), all reference to ballistic protective boots was completely removed.

Previous editions said: “...Organizations may consider providing blast resistant boots for the protection of feet and lower limbs where there is a significant risk that cannot be reduced by SOPs [Standard Operating Procedures] alone. However, [such] boots should be proven to be effective. The effectiveness and operational benefits of mine boots is still a contentious issue… the benefits are unproven. There is currently a danger that they offer a ‘false [sense of] security’.”

Are they practical and comfortable to wear?

The designs produced to date are based on two main concepts:

  • The “spider” type, which was first fielded by the French military 30 years ago, usually consist of a four-legged frame that is strapped over the deminer’s combat boot designed to provide a stand-off between the deminer’s foot and the landmine. They are shaped and made from material intended to deflect a blast away from the foot and leg but can make the wearer unstable on rough ground.
  • The other type features a sole made of several layers of protective material that adds several inches to the deminers height. These are made either as a permanent combat boot, or as an “over boot,” though they can be uncomfortable to wear and again can make the wearer unstable on rough ground.

Isn’t a deminer meant to stay behind the threat line?

That’s the idea. As such, some may see it as counterintuitive for a deminer, who has searched and cleared, to wear foot protection. During the clearance process, his or her feet should always be behind the threat line and any hazards should be cleared before their foot moves forward.

That makes it important to ensure the deminer remains on a stable footing.

What level of protection do the boots offer?

Most of the currently available boots may offer some protection against what deminers call “toe poppers,” such as the Russian PFM-1 (scatterable landmine), US M-14, Italian VS 50 or the Chinese Type 72. These contain relatively small amounts of explosives designed to injure, not kill – the theory being it’s harder to deal with a wounded soldier than a dead one.

What does the evidence say? Are they effective?

Scientific evidence suggests that these types of boots may prove ineffective against the majority of anti-personnel landmines encountered in Ukraine, such as the Soviet/Russian PMN / PMN 2 or PMD-6, which contain relatively large amounts of explosive. It is also possible that the material of the boot could a make injury even more serious by adding additional contamination in the wound.

A 2004 NATO-sponsored study carried out by the Alliance’s Research and Technology Organization (RTO) carried out a scientific assessment of all demining PPE and was rather equivocal about the utility of protective boots.

The United States Army Institute of Surgical Research (USAISR) Lower Extremity Assessment Program (LEAP) study – which offers independent scientific evidence – suggests that it is almost impossible to offer protection against the size of mine that most deminers are likely to encounter in Ukraine.

So, what’s the conclusion?

During the course of the war in Ukraine the AFU has amply shown an ability to innovate and solve technical and operational problems that others have not. Time will therefore tell if Ukraine is able to come up with a boot that proves effective whereas so many others have failed.

The LEAP study mentioned in the article seems to be biased, and there may be a point in wearing blast boots. See:

Interesting but even if it a boot held the foot intact that tremendous amount of explosive force must absorbed elsewhere on the body so a boot would only be the part of a protective system.

AP mines are much smaller that vehicle mine, with only 10-250 g of explosive, and detonation pressure of 5-50 kg of pressure.

The UN has a "safeguard' online blast damage calculator indicating even in a surface explosion with the absence of fragmentation (which an anti personal mine would have) just the smaller AP explosive charge would be fatal at a few meters. The mine clearing device would need to Absorb the worse case expected scenario repeatedly which means its probably of too heavy duty design for manual use. That detonation weigh would need to be extended away form the operator a sufficient distance to survive the conclusive blast and then PPE or shielding to protect from projectiles provided.

Its a doable engineering challenge, but maneuverability / portability / terrain flexibility would also need to be considered. I suspect they will need something of a tracked Argo size / capability as the base AP de-mining system. Something of human weighed lawn aerator style design centrally cantilevered & heavy spring tripped (like snow plow blade is) and extended past the shielded / heavily PPE'd operator by calculated distance.

It would be worth nothing though if it had enough ground pressure and misfortune to detonate antitank mine (15kg explosive).
