Abstract
Foot securing device, particularly usable in trekking boots, including a traction element which has a first portion which embraces the upper heel and malleolar region and a second portion which is curved at the foot instep region and defines grip loops for laces. The device furthermore includes a third portion which passes below approximately the median region of the sole of the foot. The device allows, once the boot has been closed, to optimally support the foot while walking, since the foot is secured in the regions overlying the heel and the foot instep.
