Z liner insoles are a scam
Fact are facts. Z Liner insoles are no different than $12 generic drug store insoles. Z Liner uses deceptive marketing to claim to be like FP Insoles however its a total fraud.
Not only does any simple at home impact test reveal the truth, we sent Z liner Insoles to a 3rd party lab for Lab testing. The results show that Z Liners are in fact not much different than cheap drug store gel insoles.
We asked the same third party lab to review and test FP Insoles vs z liner and it was confirmed that our insoles actually work.
