I have been using superfeet orange insoles to help rehab my foot injury [overloading of sesamoid region i.e. playing too hard / too often].
They are very good, and I got them from a UK website [outdoor GB] for only about 25 quid.
3rd party insoles are designed to improve your performance by injuring you less…so you can play with less injuries / less serious injuries, more often.
When picking between insoles, carbon fiber is okay because it will provide some support with a very low weight etc. The oranges will be heavier insoles, but provide more protection. That is where they can ‘improve performance’ …by being lighter (generally with the tradeoff of being less supportive].
Neither will provide any noticeable foot propulsion etc. Spending $200 on those VKTRY insoles, is like spending $1000 on Yeezy’s as ‘expensive shoes must be better for badminton.’
