Improper Footwear
Putting on poorly fitted shoes without enough support during the day would put extra pressure on your foot muscles. Along with it, working or standing on hard surfaces like concrete would create similar effects. In these cases, muscles in the feet have to work much harder to support the body weight. More importantly, improper footwear would affect blood circulation, thus cutting off oxygen and blood to these areas. This subsequently causes painful nocturnal spasms or cramps even when you are off the feet at night. [5]
