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.

Excellent quality
This is a wonderful product that was first known to me by my Orthopedist 14 years ago and I am still wearing them. Great quality, extra cushioning in the heels, easy to cut and adjust to size and easy to wear in most shoes. Spenco is Microcellular Rubber which is incredibly durable. These last me a long time, but I buy more so I don't have to constantly change them from shoe to shoe. I would highly recommend this product to anyone with foot pain.

Arch Support
"I've been using the Spenco Polysorb Heavy Duty insoles for a while now, and they are incredibly comfortable. They provide excellent arch support and cushioning, which has significantly reduced foot fatigue, even during long days. My feet feel more supported, and I notice less discomfort after being on my feet for extended periods. Overall, I highly recommend them for anyone needing reliable foot support."

comfort
bought these insoles as my podiatrist recommended. I am so satisfied with these and cannot believe how comfortable they are. I have tried many others from stores I bought my shoes from and these put all those to shame. Highly recommend you try them!! I have plantar fasciitis and the heal support is awesome, they are easy to cut down to size and come really close to the size they say they are. The pain relief was pretty much instant.

These are great while they last
I work in fire service and have different boots/shoes for different jobs. My overnight station boots are slip on blundstones. After about a year the stock insoles wore out so I needed something good to replace them with. I came across these and seen the great reviews. I ordered them, cut them to size and put them in my boots. They were great... much better than the DR S brand ones I tried before. Down side to these is they dont last! My slip on station boots dont get a ton of use yet these insolves after 3 months need replaced because the ball area has now wore through. If these held up longer I would have given them 4-5 stars. I may even try them again if what I go to next doesnt work out. Just wish they would last longer.

Great comfort and support for arches
I'm a long time fan of Spenco insoles and have had them on and off in my shoes for 35+ years. I really like these Polysorb insoles! As soon as I put them in, it felt like I just bought a new pair of shoes! So supportive and comfortable! Highly recommend them to others with flat feet like myself.

saved my work boots from the trash bin
I was originally looking for some new boots but couldn't seem to find a pair that wouldn't hurt my feet(I work over 12 hours per day on my feet as a diesel tech)my year old boots were starting to make my feet hurt real bad,almost to the point that I was going to see a doctor(my left foot was popping and in serious pain).Before I decided to see a doctor I was reading some reviews on the internet about some of these insoles garanteed for a year and were the best that any body had bought (I thought yeah right)I can destroy an insole in less than two weeks with the way I use my boots,But I decided to give these a shot anyway(glad I did)these insoles from the first time I used them helped me get rid of the pain I had in my feet which was a scarry kind of pain to say the least(All I'm saying is that I've worked many hours in pain and hated my boots untill now)If you've spent money on insoles like I have(gel,foam,arch support,and whatever else I've used over the last several years to help rid my feet of pain)I would only recommend you to buy a pair of these and just test them out.Understand this though(I never thought that these insoles would work the way they did and I was very sceptical to say the least)after all I was about to see a doctor for the pain I had, and I really didn't think that all of the reviews were true but let me tell you they worked for me(the most comfortable,nonslip,and best foot support that I have ever found in an insole)and I only paid $10 each through amazon.If there is a better, longer lasting insole out there for under$10 dollars (I never found it)but let me tell you if your feet need help and your thinking about throwing your boots away and even seeing a doctor, try using these first and maybe you'll save your self some time and money(and in my case alot of pain from working 12 or more hours on my feet 6 to 7 days a week)
