Определение flat feet в Английский Язык Английский Язык словарь
A physical condition of the feet where the arches have collapsed and the sole of the foot is in full contact with the ground
Flat feet, also called pes planus or fallen arches, is a condition in which the arch of the foot collapses, with the entire sole of the foot coming into complete or near-complete contact with the ground. In some individuals (an estimated 20-30% of the general population) the arch simply never develops in one foot (unilaterally) or both feet (bilaterally). It should be noted that being flatfooted does not decrease footspeed. Horses can also develop flat feet
a medical condition in which someone's feet rest flat on the ground because the middle of each foot is not as curved as it should be
