First of all, the principle of inner height-increasing shoes is physical increase. It’s not about making you really taller. To put it simply, it's like a woman's high heels. You still have your original height after taking off the height-increasing shoes. It is recommended that you go to the physical store to experience it for real. Everyone's situation is different. Can't make a conclusion either. If you need it, you go and try it. It feels pretty good, and it will be useful to you. A question, from different angles, everyone has different opinions. I hope what I said can help you.
