Why does my foot go numb when cycling?

Numb feet when cycling can be quite a problem and there can be several reasons why your foot may go numb while cycling.

Some of the more common causes are:

Pressure on Nerves:
Prolonged pressure on nerves in your foot can lead to numbness. This can occur if your cycling shoes are too tight or if your feet are positioned in a way that puts excessive pressure on certain nerves. Compression or entrapment of nerves, such as the tibial nerve or the peroneal nerve, can occur during cycling. This can happen due to repetitive motion or prolonged pressure on specific nerve pathways.

Feet Swell:
During prolonged swelling feet swell, some more than others. This can also lead to pressure on nerves causing a numbness.

Poor Blood Circulation:
If your cycling shoes are too tight or if they restrict blood flow to your feet, it can cause numbness. Inadequate blood circulation can deprive the nerves of oxygen and nutrients, resulting in numbness.

Incorrect Foot Position:
Improper foot alignment or positioning on the pedals can contribute to numbness. If your foot is excessively pronated (inward rotation) or supinated (outward rotation), it can put pressure on specific nerves, leading to numbness.

Vibration and Shock:
Cycling on rough terrain or using a bike without adequate shock absorption can transmit vibrations and shock to your feet. These vibrations can contribute to nerve irritation and numbness.

Management of numb feet during cycling:
Ensure your cycling shoes fit properly and are not too tight – this is the most crucial element. They should provide enough room for your feet to move and allow proper blood circulation. Pay attention to your foot position on the pedals. Make sure your feet are properly aligned and not excessively rotated. Take breaks during long rides and try to move your feet and toes periodically to improve blood circulation. Use shock-absorbing insoles or cycling shoes with better cushioning to reduce the impact of vibrations.
