## Description

Insoles for workers seeking lasting comfort, cushioning and support. Provides targeted shock absorption to soften heel impact.

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: 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.

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
*by M***S on January 18, 2026*

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.
