Question: I have a 7 inch wrist, should I buy the 7"small or the 7&1/2" medium? Not sure if it is better to have it just fit or have some wiggle room?
Document: I've had several injuries that challenge my balance. This wristband seems to help me do things that I would not have tried. Don't know for sure if it is working but psychologically, it works for me!
Answer: no
