I'm a 27 year old male. I have returned to gymnastics after 3 years out and find that I get severe cramp in the arches of my feet. It seems to occur if I point my toes too hard and for long periods of time. My feet don't seem to be as flexible as they used to be as I used to have a much better toe point before. As I have to train in barefeet, I've also noticed that they can get quite cold sometimes. Can anyone help?
