Bests & Worsts Reviews from Amazon

I have NEVER used these types of shoe liners before but I recently got orthodics that I like to wear in my mary janes and synthetic insoles ALWAYS stink up FAST when I don't wear socks so I decided to get these to see if it would delay this inevitable result. So far so good. I wear a 10.5-11 womens and I ordered the Size 2. They stay up because at the back of the heel it has this little rubber film, however where the seam of the elastic meets, it usually digs into my skin and starts to make it sore. These were just a hair to tight for me and that's why I'm giving 4 stars. 4/9/14 Update: When I wrote the review above, I had only worn these brand new, never washed. I recently went to Target and saw some liners that looked promising. They were less expensive than these and came in a pack of 3 in pink, black and white. They were 100% synthetic material and also had a little rubber pad at the back of the heel. They felt better when wearing them at first, but they kept slipping off my heel. GRRRRRRRRR. Also, I could not get them to stay hidden when wearing my mary janes no matter what. ALSO my feet sweat a lot in them which I felt didn't happen in these. I had worn a pair for about 2+ days without them getting stinky. (yeah, I know, gross and TMI) I did not take a chance with the Target ones. All in all, I felt I wasted my money on the target ones and here I am buying another set of these. One more thing, after I washed them and wore them, I did not have any problem with the seams and they didn't feel as tight. Who knew? I wore them with the same shoes so I know it wasn't a shoe issue. The rubber heel slip protector is about 3 times the size on these than they are on the Target ones. I changed my rating to 5 stars.
