Thank you for making such a great product for me! I got the single medial model and it's allowed me to run comfortably again. I think that was maybe 8-10 years ago. I wonder if the double double will fit just as easily in my shoes/boots as the medial model. The only issue I've had has been when using high ankle shoes/boots that push the peek rods into my ankle but I just put a little pad there to prevent the rubbing. Thank you again!
