Review: 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.
Review: AWESOME! I can wear NORMAL SHOES AGAIN! - I have never found an insert that actually worked well enough to say my feet 'didn't hurt'- NOW I HAVE! They do take up a decent amount of space in the shoe, so ones that aren't very deep will likely not be able to accommodate them and your feet. I actually measured my shoes: I have 'thick' feet and my shoes that were only 2.5" deep (or less) will not work, 3" or more were perfect (measured without any insole). These take up about 1/2" of insole space, I could put my shoe's original insole on top of them- but they were far more comfortable without. I was truly amazed at the width difference between the two! I was certain I needed to trim the Polysorb insoles width-wise: NO WAY. These totally provide support to the sides of your feet that most 'retail' shoes do not. (Thus the discomfort when I added the original insole for 'extra' padding- my foot was wobbling in that extra space) I have always had to wear super expensive orthopedic shoes if I was going to be on my feet for much more than a run to the grocery store or so, at least if I wanted to be able to walk the next day anyway. Much more than an hour on my feet or two miles walking and I would be in agony. I do not have fallen or high arches, and I strongly recommend anyone having foot issues either go to a Dr, or at least do the 'wet foot' test to determine your type of arch. I thought I did have arch issues since it was the arch of my foot that was KILLING me- but 'arch supports' were useless (and sometimes very painful). I have tried nearly all of the 'walking shoes' on the mainstream market (Sketchers, Nike, Reebok, etc.) and each lead to horrific pain so they sat in my closet. I promptly put these inserts in within 20 minutes of their arrival- NO PAIN whatsoever. I have not put them to the ultimate test: I work at a school so I spend 6 hours a day on hard surfaces and I walk 3-4 miles/day, but I have done enough walking to say that these make a HUGE difference: I have worn orthopedics ONCE since they arrived (and that was because I really wanted to wear sandles that day).

### ⭐⭐⭐⭐ Arch Support
*by C***A on January 17, 2026*

"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."
