I'll put in my 2 cents worth, as a runner and swimmer I get cramps in my legs and calfs at least once a month,one way is to drink about a small cup of pickle juice right from a jar of pickles(I usually put a straw in it a suck for 30 seconds or more and I HATE pickles!!),this seems to work and some schools even do this for their sports teams.The other way to get rid of cramps in legs or toes/feet areas is,the next time you get a cramp in said area pinch the area below your nose and above your upper lip and pinch HARD for a least a minute ,this really works,it's like a restart button for your brain that tells the brain I'm hurting let's fix the problem.
