The ISS sole

Our footwear production for diabetics is based on the patented ISS sandwich-structured sole, which contains several layers that prevent blisters through their synergistic effect. The principle is that the weight of the entire body is distributed over a self-moulding and flexible layer over a much larger area than in conventional footwear, thus eliminating point loads on the bottom of the foot.

The ISS sole consists of three to four soft flexible layers: one of them - the outer layer is a hard-to-remove polyurethane skeleton, followed by a 3-6 mm thick self-mouldable layer, on top of which is a permanent flexible 8 mm thick layer of shaggy latex, on top of which is a textile and leather insole. The polyurethane skeleton has a low weight and high durability. The integrated soft layers do not wear out over time like regular insoles, they absorb shock, and vibration and insulate thermally. All blisters will fade over time and no new ones will form by wearing this type of footwear. The sole can also absorb local pressures, for example at the heel spur. The shoes are available in several designs with different hoof widths, but always with the ISS- DIA, ISS -FLEXI, or ISS- BIO sole.


Dia shoes with the EPUR ISS -DIA sole were clinically tested with the conclusion that they can not only delay but also prevent lower limb amputation of the diabetic foot, because the thickness of the soft layers is an incredible 16 mm.
