Vasyli Armstrong Diabetic Orthotic Insoles The Vasyli Armstrong Diabetic Orthotic Insoles are unique orthotics that are a revelation for sufferers of diabetes and have been professionally designed by the Vasyli think tank team. Where conventional footwear and insole technology fails to address the key problem areas for the diabetic foot, the Vasyli Armstrong Diabetic Orthotic Insoles does so effectively. The Vasyli Armstrong Diabetic Orthotic Insoles address the key problems that diabetic feet suffer from -shearing forces, friction and pressure. By utilizing patented Glidesoft technology, this unique combination of construction and materials has been scientifically shown to reduce shear pressure in the forefoot area by 50% and dramatically reduce the onset of plantar ulcers, whencompared to conventional diabetic insoles. How Do The Vasyli Armstrong Diabetic Orthotic Insoles Work? By using a unique design with Glidesoft technology, the dorsal surface of the insole moves with the plantar surface of the foot. This is achieved by a clever design of five layers of materials sewn together in such a way as to allow the top layer to slide on top of the lower layers. The Vasyli Armstrong Diabetic Orthotic Insoles are thickly constructed orthotics made from five layers of material; The top layer is 'Outlast' material, a constant temperature material cover 'Plastazote' layer for 100% plantar surface contact Shock absorbing layer Teflon layer The bottom layer is the 'eva base' heat mouldable material The Vasyli Armstrong Diabetic Orthotic Insoles have also been clinically proven to assist in the prevention of plantar ulceration by addressing the shear forces in the foot as described. Plantar pressure reduction is also addressed utilising 'Plastazote' to provide a soft, self moulding full plantar contact environment for the high risk diabeti foot. The 'Outlast' material helps ensure an even distribution of temperature accross the foot helping to eliminate hot spots. The Vasyli Armstrong Diabetic Orthotic Insoles can be heat moulded using a heat gun The Vasyli Armstrong Diabetic Orthotic Insoles should be used in conjunction with correct diabetic footwear and regular medical check ups. Sizing Information Please use the following guide based on shoe size to determine your size and select the required option from the drop down menu above. Please note the Vasyli Armstrong Diabetic Orthotic Insoles are trimmable if fractionally too long.
