Pretty good for the price. A minor drawback is this isn an insert and not an insole. Had to remove insole in gym shoe as adding this was uncomforable. Now without the forefoot cushioining a minor "hardness" in shoe. Decent arch support. Also have a pair of Tread Lab insoles which offer more arch support and forefoot comfort and support due to being an insole but with 8X the price. Actually, good support for an insert, regardless of price. Curious to see how it fairs in the longetivity category.
I got it for my father he have flat foot and it effects his back a lot, since he used it he feels much different and light weight in walking. And it takes the feet shape.
No more pain like other foot supports he got before
