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.

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."

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.

I didn't realize how much I enjoyed these.
Amazon claims I've bought these 3 times, but searching my order history only shows the last 2, with the last being a week ago, and the previous time 2 years & 9 months ago. I was checking my order history, because I remember these were a fast solution to foot pain I was having back when they were first recommended to me, but the subscribe and save price is tempting, and I didn't know how often I might need them... Feet were hurting again and in the same way they were years ago, even though I had recently bought new shoes, so I thought I'd try these again, and within hours, my foot pain was gone. When I first experienced this pain, I went to a podiatrist, and his first reaction was to try to exercise my health insurance by operating on my feet... I got a 2nd opinion from an orthopedic surgeon, who said "My feet haven't changed/the extra bones in my toe joints have been with me all my life, so cutting them out is NOT the best course of action - I'd be better off with these inserts and foot/toe exercises. I ordered them then, started PT for my toes & feet, and 4 days later, I was wearing these insoles for the first time. My pains went away almost immediately (and I started slacking off on the toe/foot exercises). It took nearly 3 years for me to wear out the last set of these enough that it bothered me bad enough to look for solutions, so I don't think I'll subscribe, just order a few spares to have on hand, for when my feed hurt again, and then restock my shelf as needed. Either way, these WORK, or at least they did for me and very well!

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.
