The peroneal nerve controls the muscles that lift your foot. This nerve runs near the surface of your skin on the side of your knee closest to your hand. Activities that compress this nerve can increase your risk of foot drop. Crossing your legs. People who habitually cross their legs can compress the peroneal nerve on their uppermost leg.
Foot drop may occur if you cross your legs often. It may also happen if you have recently lost weight and are able to cross your legs again. Tight bandages, braces, or casts may cause foot drop. Athletes with hard leg muscles could develop foot drop. Foot drop may be genetic (passed on to you by your parents). You may have foot drop if you have had a stroke, diabetes, or a mass blocking your nerves. In some cases, the cause is unknown.
