Have you tried simply working on mobility? I used to have a hard time squatting deep without raising my heels but once I really made an effort to do mobility work I saw improvements very quickly. Just checking if it’s something that could be fixed without special shoes before we go into that, moving on…
A board doesn’t support the entire foot and that’s not good in the long run, once you start handling some serious weights it can become really bad for the foot. Another problem is that the board just means one more thing you have to think about and when you’re walking out with a heavy weight you want as little distraction as possible. The board should only be used as a test. If the board fixes the problem, buy shoes with elevated heels.
Different shoes have different heel-height so try out a couple of different ones if possible to find what’s best for you. Olympic Lifting shoes tend to have very high heels (Do-Win probably have the highest). Then there are some powerlifting shoes like Crain’s Power Squat or Inzer’s The Pillar, those have slightly lower heels.[/quote]
According to my doctor, it is a short achilles tendon and not a flexibility issue in the ankles. I have tried stretching and other things, but it has not done anything to change the issue.
