Thanks for your reply! I definitely want to look into purchasing the glass ones in the near future, as it is definitely a worthy investment. I have tried walking about with the silicone ones and agree that it is painful because of their length. And after all, for me, the length isn’t the issue, its the width!
And yes, I’ve had them since February or so, but being so busy at school its hard to be consistent with them. I’m currently stuck on the purple one, as the pink one is very painful to even get in. But I still feel it is helping!
