Are the height increases mentioned on your website accurate?
The numbers on the Height Increasing Altitude Shoe website are accurate.
The shoes themselves can be tested with an accurate ruler. It is possible that the height increase may be slightly lower if your body weight causes the soft material in our Altitude Shoes HQHI (High-Quality Height Increasing) Insoles™ to compress a little. That being said, this compression effect will not have a dramatic effect.
