I've recently been experiencing pretty intense arch cramps in my skates, such that my legs get a bit shaky. Is this a sign that there's something wrong with my skates? I've never been super happy with these skates, but the idea of getting new skates is a bit daunting. For reference I'm an adult skater returning to the sport working on all singles and various spins (sit, camel, back spin, back sit etc). I'm in a cold climate so a part of me wonders if it's just the cold of the winter (rink gets very cold when it's below freezing outside). Any advise would be appreciated!
