Quick question: I've noticed some guys wear ankle supports and I was do people wear them to prevent injuries or are people wearing them because they already have injuries? If the latter, what constitutes an injury that you want to protect. I landed on my foot oddly yesterday and it hurts stepping down on it. I don't have lessons until Monday, and I was wondering if I should get one in the hopes that either my foot will heal by then or I'll have something to prevent it from getting worse during lessons. Thanks!
