State-of-the-art combat boots that protect wearers from the full impact of landmines have begun rolling off the production line in Singapore.

The Blast and Fragment Resistant (BFR) boot weighs less than most combat footwear and has more than two dozen shock absorbing layers of aluminium and steel to limit the skeletal and soft tissue damage caused by a landmine blast.

Designed by Singapore-based inventor Andrew Vaz, aged 45, samples of the high-tech boot have already been sold to a dozen countries, including Spain, Turkey, Sri Lanka, Saudi Arabia and the United States.

The British Royal Military College of Science recently carried out a number of tests on the boot with anti-personnel landmines containing up to 70 g of high explosives and the blasts did not penetrate the sole of the boot.

Pilot production at his company's 40,000 square foot plant in Singapore got underway last month and the boots are expected to cost around US$160 per pair.

The plant employs about 30 staff and has the capacity to produce 120,000 pairs per year at full capacity.
