Foot cramps are an involuntary contraction of the muscles in the feet. They occur most often in the arches and toes, and can last for seconds or up to a minute, says Dan Michaels, DPM.
They have a variety of causes, most of which are not serious. However, if you frequently get foot cramps you should speak with a doctor to rule out serious underlying conditions like liver disease or nerve damage that can make foot cramps worse. "If you're experiencing foot cramps, it's very likely from muscle tightness, fatigue, improper shoes, or dehydration," Dr. Michaels says.
