Surfed cold, but not frigid, RI this afternoon, and my feet cramped completely . . . Like two blocks of wood. Thus happen to anyone else in the cold? I had Drylock 7 mm boots with dive socks on, they do make he boots very snug . . .
Significant temperature change, dehydration, low potassium and low calcium can cause cramping in calves and feet.
I had the onset of cramping in the arches of my feet a couple times last week while out. To stop, I'd stretch the arch of the cramping foot by pointing the big toe upward toward my knee. Cramping in foot or calve would happen sometimes while swimming laps.
Loose the socks, and loosen the strap going across your foot. Whenever this has happened to me it has been because of poor circulation and not because it was cold.. Either way you should still be drinking water pre and post sesh.
Oh yeah, absolutely. Cramps are typically caused by either electrolyte loss or fatigue. If you're in the cold you're shivering and burning a lot more energy just maintaining body heat. Eat well and hydrate before any surf, especially in the cold. I find it helps.
