Those patients allocated in the experimental group will be supplemented with a external shoe lift in the contralateral limb in their conventional shoes to compensate the differences with the affected foot (using a offloading device to active ulcer).

Those patients allocated in the control group will not be supplemented, they will be treated with a standard of care treatment.

Height compensation will be made with cork or EVA (polyurethane + Ethylene Vinyl Acetate) depending the characteristics of the shoe. It will be made by the same orthophaedic technician. The prescription of the heigh of the lift will be made with the patient in a barefoot standing position, a calibre will be used to mark the femoro-tibial joint in both lower limbs in order to rule out the asymmetry. After this, the patient will shod the offloading device in the ulcerated feet and their conventional footwear in the other foot (with the use of their own foot orthosis). 5 millimeters splints will be added under the non affected footwear until the previous mark in both limbs been balanced. The difference in the heigh between limbs will be assessed measuring all the splints used previously

Evaluated by the same clinicians, defined as 100% of epithelialization in absence of exudate

Evaluated by the same clinicians, defined as 100% of epithelialization in absence of exudate

Two pedometer will be used (one inside the vendaje and the other into the offloading device)
