"I ordered the women's size 5-5.5 but they are too short for my daughter's size 5 shoes. There is about a quarter to half inch gap between the end of the insert and the end of the shoe, and a similar gap on the size 4.5 shoes I tried them in. They seem like a good quality product, but unfortunately we won't be able to use them."

"I have developed a very sore foot recently that I’m pretty sure is plantar fasciitis. I did some research on my favorite pair of sneakers and found out that they are “zero drop,” meaning they don’t have much support. I decided to add these inserts. They made them wearable again! At first the spot with the most intense arch support felt weird/misplaced, but after a day of wearing them they felt fine."

"I probably should not have ordered this insole. It is specifically meant for people that need firm arch support - and I mean FIRM! The area from the beginning of the arch all the way to the end of the heel is a padded stretch of hard plastic. I have normal arches, so the hard "artificial arch" provided by this insole is uncomfortable for me. I find it to be like hiking on a floor of bowling balls.
.... but ....
These insoles are made for people with flat feet or super high arches. I believe this design will help people with those conditions. But beware - the unyielding hard form could lead to other problems, including blisters, shin splints, etc. If you are new to rigid arch support insoles, take your time getting used to them before you try major expeditions. Once you have broken them in, and once your feet get used to them, you will be fine."
