We4U Products - 1 Inch Height Increase Insole - Invisible Heel Lift Pads - Silicone Gel Inserts Socks for Men & Women Without Holes

Top of the silicone split completely open upon first use (I have fairly skinny feet so no excuses there). Tried to keep using but they’re not usable even in a shoe because they don’t stay put without the top part being intact.

I liked this product for that fact that it is attached to your foot so it doesn't slip anywhere. However if your shoes are narrow, this may not feel comfortable. At times, it felt a bit wobbly to walk in these. As these are worn under socks, when you take your shoes off, it is a bit more difficult to take your feet out the shoes as it is tight. Overall, it is not for everyday use but if you have certain events where you feel it might be good to feel a little taller to give you abit more of a confidence boost these are ok.

I had been suffering from heel pain when walking for a long time, these silicone socks have really helped soothe the heel and are very comfortable to use. Will be buying more.

It slips a lot, I couldn't walk properly. Tried different ways too, no luck..

Doesn't seem to fit amazingly well, I'm a size 8 but the insole sock itself kind of slips about. Meaning that you sort of slip.Plus the product itself I can see the rubber damaging pretty easy in the sleave.

Filled purpose providing great comfort to sole of my foot, I am flat footed so my feet ache easily. Bought these to help counter that issue and help perfectly.
