Best lifts on Amazon?

Edit Post

A few years ago, I was using some decent lifts in boots and was probably gaining about 3.5 inches. Pretty good when combined with boots. I can't recall what those were, though, and the ones I've tried since have either been flimsy crap that easily flatten. I use these ones for dress shoes: https://www.amazon.com/Mendez-Premium-Height-Increasing-Insoles/dp/B07CZ2GS2L/ they're reliable and very strong but they only give a small boost and I'm looking for something more substantial for boots. Any suggestions?

Haven't tried eBay, but I can look there too. I probably should've asked more for the brand of the lift than specify an outlet; I just figured that Amazon typically has everything.

Thanks, man. Have you tried those? I have a couple of pairs of Calden dress shoes that are height enhancing. They look quite nice but the actual lift isn't as much as lift inserts tend to be. How legit is this brand in terms of giving you 13 cm(!) boosts?
