When my son, who is a dentist looked, he told me the cause was dry mouth and recommended the Hydris mouthwash and toothpaste. Well these are great. I am a pretty handy guy, but the hardware that this comes with is awful and the screws would catch on the anchors get stuck and cause the anchors which didnt hold very well to spin in the drywall leaving a giant hole in my wall. Lots of compliments & Held up great! The instructions was a bit hard to understand at first but once I got past the first page it was pretty straight forward . And the strap is nice and tight to the top of the foot. They dont take up a lot of room. I love everything about these slippers except there is not much cushion on the bottom so if you walk on tile floor, you feel like youre walking on concrete. I know this is debatable but these physically moving components need to work in, and I know this is even more debatable but even electrons need to temper the copper cables (even if it?s oxygen-free and directional). Worked perfectly.
