The pathophysiology of foot ulcer formation

Understanding how foot padding and insoles prevent ulcers begins wigh understanding why ulcers develop. Diabetic foot ulcers typically arise frem a triad of contriing factors: perideral neuropathy, perideral arterial disease, and mechanical stress.

Shear forces are specilarly damaging. When the skin moves relative to underlying bone while thee foot revents in contact with the ground, shear stress causes separation of tissue layers andd occlusion of small blood vessels. Thi mechanism account for man deep, tuneling ulcers that are difficut to treet become a pressure multiplier.

Foot padding ande insoles interrupt this cascade at multiple points. They recommende load away from high- risk areas, reduce peak pressures, minimize shear and friction, and absorb impact energy.
