Repeat user of these
These are the best insole i've used. I'm a big dude, about 300 lbs. They make my boots comfortable. The insoles lasted for about 6-8 months in my daily wear work shoes before i could tell they were not as supportive any more (my foot, ankle, knee, and back pain started to come back). The pains cleared up in a couple days. Easy to trim. I had a prior insole to copy and they fit perfect. The sizing seems spot on, but i'm at the smaller end of this insole so i have to trim a fair bit. Size 12-13.5 I have used Spenco's gel insoles before which wore out faster and were less comfortable.

Great insert for planter fascititis
Great insert to use if you struggle with planter fascititis. They have great support and can be interchanged between shoes. Great price to ensure comfort while wearing shoes.

These make my shoes and walking more comfortable!
Aftermarket insoles have been a part of my life for awhile now! They are a small item that can help make me feel better, IF, they are good enough. To start off with, I have always had flat feet, am 6 feet, 3 inches and weigh about 260 lbs. So my feet and joints take a beating. The lighter the shoe and the more cushioning and support can make a serious difference throughout the day, at the end of the day and evening and even in the morning when I stand up and take my first few steps. I have tried a lot of insoles. In the past I have gone with less expensive ones, only to be disappointed with the lack of support, cushioning, stability and durability. :( So a few months back, I saw these Spenco Heavy Duty insoles. While their appearance won't overwhelm you. The materials they are made up of are pretty robust, don't compress to nothing and really provide the extra cushioning and support I really need. They are not the cheapest, nor the most expensive. They seem to have a mid position pricepoint. So considering how solid they are and longer lasting, I consider them a good value. :) I feel comfortable recommending these to others. If they can help me feel better with my particular body size, weight and feet, I think that you may benefit from these as well :) They may even allow you to walk more comfortably and thus you may add more steps to your day - which is something that can benefit a lot of us! Good luck!

Too expensive now, thanks to tariffs
These work really well, and I've been buying them for years. Today, thanks to tariffs, they are 30% more expensive than when I bought them last year. Will now shop around for something more affordable.

Wow!
I've purchased dozens of soles/insert the past 2 decades. Candidly, these are, by far, the most comfortable. It's too early to determine if they'll last, but 2 hours in; nothing short of amazing.
