{{DISPLAYTITLE: Replacement Insoles For Running Shoes}}
[[File:Testing Insoles.jpg|right|thumb|200px|]]
I [[Shoes| tested many different running shoes over the years]], and with a few exceptions, I found that they don't lost anywhere near as long as I would hope. The main limit to the lifespan of a running shoe is generally the breakdown of the foam that results in less cushioning and more importantly uneven cushioning. This uneven cushioning tends to twist the foot in odd ways, and I suspect is a factor in running injuries. Most running shoes have their foam cushioning split between the midsole and the insole. The insole is one of the cheapest bits of a running shoe to make, and because it's next to your foot it's often made of softer foam to improve comfort. Unfortunately, this soft, cheap phone breaks down quickly, and can be a limiting factor in the lifespan of your running shoes. In most shoes the foam insole is removable and easily replaceable. Or at least, it would be easily replaceable if you could find a replacement! The problem with finding a suitable replacement insole is that most of the products on the market are sold as expensive "miracle cures" that attempt to modify your [[Running Form]]. I've tested a number of different replacement insoles with the goal of finding some that can extend the life of your running shoes when the original insole starts to wear out. I've also include a table of some sample insoles from shoes I've recently tested at the bottom of this page. It's important to know the thickness of your current insoles, as the replacements could change the way your shoes feel. The replacement insoles could increase or reduce the amount of drop, which may or may not be desirable. They could change the shape of the arch; an arch is a naturally strongly structure unless you push up from underneath. I'm concerned that "arch support" quotes can irritate the foot and cause plantar fasciitis issues. The other obvious issues to look out for are the overall thickness which could increase or reduce the volume of your shoes, and the weight (most replacement insoles are likely to be quite a lot heavier than the originals.)I've also reviewed [[VKTRY Insoles]], which use a carbon fiber plate to improve [[Running Economy]], but I don't consider them a replacement insole in the way the other products reviewed here are.
=What I Look For=
The primary goal of this review is to find a simple replacement for most original insoles. Generally, I'm looking for something close to the original, rather than an upgrade. However, I was also curious about the possibility of a more expensive insole actually improving a running shoe. Most of the products I tested claim to be an improvement over the original, something that I found was rarely borne out in practice.
=Sample OEM Insoles=
Here are a few insoles from shoes I've tested to give you a sense of what a "normal" insole is like.
