From personal experience, if you have fallen arches something soft like the stock lunarlon insoles offer almost no support and have almost no shock/impact protection for your joints. They do feel soft on your feet so I understand the comfort aspect.
The material of the game changers is harder, and after a few days it helps your knee and hip issues for sure.
Kinda like eating vegetables, no one really likes to do it but the benefits are very beneficial.
I am using these orthotics now.
As for the price, the material they use doesn't come cheap.
The shock absorption properties coupled with the ability to remold/form to your foot is hard to match at that price point.
The gel insoles and other options do feel great on the foot, but don't do much for the rest of your body.
I've tried every insole fp and remind make. These ones work best for my situation, if your arches are normally flat, the flat kingfoams work great.
