Let customers speak for us
from 227 reviewsAs a 76-year-old male with peripheral artery disease (PAD), I walk 2 miles daily. Due to reduced blood circulation, I often experience intense calf pain. It’s well-known that people with PAD develop kinetic impairments from an altered walking gait over time. Scientific studies show that PAD can reduce walking torque and diminish ankle plantar-flexor power during push-off.
After trying carbon insoles and MFM Performance insoles, I found the MFM insoles to be just as effective. My walking times have dramatically improved, and while the calf pain is still present, it’s noticeably diminished—likely due to the improved walking kinetics provided by the MFM insoles.
These insoles aren’t just for people with PAD. They’re designed to support anyone who walks regularly, whether for exercise, daily errands, or long walks. They provide excellent cushioning, stability, and enhanced walking mechanics, making every step smoother and more efficient.
I highly recommend MFM insoles for anyone who wants to improve their walking performance and comfort. They’ve made a real difference for me, and I believe they can do the same for anyone looking to take their walking to the next level.
I tested the MFM Performance Insoles with two shoes—a Brooks Ghost Max and a Mount Coast R1—throughout my training and into the Badwater 135 in Death Valley, and they delivered exactly what I needed: excellent cushioning and shock absorption without adding bulk or introducing wobble. Fit was straightforward (minimal trimming), arch support felt neutral to moderate, and the insoles kept my stride consistent on road . Even in extreme heat over long hours, they held their shape, didn’t cause hot spots, and dried quickly after sponge downs. I recommended for runners who want extra protection without compromising a shoe’s natural ride.
I Was searching for flat, zero arch, fillers (3 mm, 4.5 mm) for my work boots for a while. I bought those leather sockless with Carbon fillers from turkey/India and they turned out to be a waste of money. These are great, I can move from boot to boot and they don’t fall apart or “melt and stick" to my boot sock liner. These are solid! I’ll get more as I need them, great buy. Happy I found this company. My boots fit a lot better. I'm very happy with this product. (I needed these in my Navy FLT Deck boots years ago, dang it!)
Exactly what I was looking for…solid shoe filler. I am very happy these are firm thin insoles that fill in my Asics shoes perfectly. I have very narrow feet and this solution is great. I plan on ordering more to ensure I have reserves.

They still haven't arrived, but I got a prompt reply from customer service and they will try to solve the problem.
Put these on my redwing work boots and immediately felt a difference it no longer pains me to be on my feet for an extended period of time.
WIDE Run 619 Shoe Inserts - Thick, Firm, Shoe Insoles , Zero Drop Profile, Traditional Shape, Foot Forming
Simple and effective insoles!
Run 619 4.5mm Firm Shoe Inserts | Zero Drop | Foot Forming | Traditional Shape
Fast shipping and a great insole. Love the firmness of these insoles. A great alternative to the overly soft and "squishy" insoles that come with most shoes.
While these are great for general cushioning during long walks or runs, I'm using them differently. I'm inserting only 1 in my left shoe to address a leg length disparity. Works great (although you may need to size up a half size.) I like these better than many of the other lifts/inserts, as they are the same thickness for the full length of your shoe, totally flat, zero drop.
I really liked these insoles. I got they for a minimal zero drop pair of golf shoes, that I walk several rounds a week with. I love that they were thin, zero drop, wide and without added support. Just what I was looking for. Thank you.
Really great Insoles and service. I’ve pitched the stock insoles and now use these. They are much better support and the cover doesn’t wear out as easily as the stock insoles.
Work on my feet all day & these were used as an inserts under my Birki’s cork sole…they work amazingly well ! I’ve gone thru a number of brands that didn’t work because of them being too soft . Well done Run 619 ! Great product .

Understanding the Benefits of Our Insoles
At Run 619, we started with one mission: to build flat, no-arch, zero-drop insoles that deliver simple, foot-forming performance without changing the feel of your shoe. That’s still at the core of what we do. But now, for runners and active users who need more structure, we’ve introduced a completely different kind of insole—one with true arch support, a shock-absorbing heel pad, and a base designed for stability and durability over long miles. It’s a major step beyond our original designs—but still built on the same zero-drop platform. Whether you want something flat and minimal or structured and supportive, we make insoles that help you move naturally and stay on your feet longer.
Flat, Foot-Forming, and Zero Drop
Our original insoles are minimalist by design—flat, firm, and built for those who want a simple, dialed-in fit. With no arch, a traditional shape, and a zero-drop platform, they’re ideal for replacing worn-out insoles, pairing with orthotics, or fine-tuning your shoe’s feel. Available in three thicknesses (3mm, 4.5mm, and 6mm) and two widths (regular and wide), so you can choose the level of ground feel or underfoot support that works best for you.
Built for Performance. Backed by Support.
Our new Performance MFM Insole is made for runners who need real structure and all-day durability. A cushioned PU heel pad absorbs impact, while the medium arch and firm 5.5mm base deliver stable, responsive support without feeling bulky. Still zero drop—so your stride stays efficient, even when the miles stack up.
