Thought Zero Drop Arch Support Insoles Didn’t Exist?

If you’ve ever searched for zero drop arch support insoles, you’ve probably discovered something strange — they don’t seem to exist. You can find flat minimalist insoles, and you can find supportive insoles that raise your heel, but try to get both — a true zero drop profile with real arch structure — and you hit a dead end.

That’s the gap that inspired our Run 619 Performance MFM Insoles. Designed for runners, hikers, and everyday movers who want balanced support without breaking their natural stride, the MFM bridges what most brands treat as opposites: zero drop geometry and functional stability.

Why Zero Drop and Arch Support Rarely Go Together

Most insole makers start by lifting the heel to build arch contour, which immediately breaks zero-drop alignment. The logic makes sense — if you raise the arch, the heel follows — but it changes your foot’s natural position and adds an angle that doesn’t belong.

Zero drop, by definition, means flat from heel to toe. It’s meant to keep your posture neutral and your stride honest, aligning your body from the ground up. That’s why so many runners and barefoot-style enthusiasts swear by it — it lets your feet do their job.

The problem? Flat insoles often go too far in the other direction. They remove every bit of structure, leaving your foot to work overtime to stay stable. After a few hours or a long run, that minimalism can start to feel less “natural” and more “fatiguing.”

The MFM Solution

The Run 619 MFM Performance Insole was built to solve that. It’s a true zero drop design with a balanced midfoot contour that supports your arch without forcing it. The heel sits at the same level as the forefoot, preserving alignment while adding just enough structure for endurance and stability.

Each pair features:

• A firm, high-density EVA base that stays consistent under pressure.

• A TPU heel frame for subtle stability.

• A responsive PU heel zone that delivers balanced support over long mileage.

• A breathable, anti-odor top fabric that feels clean mile after mile.

It’s not about “fixing” your foot — it’s about working with it.

Tested the Hard Way

We’ve put thousands of miles into the MFM insoles — from Badwater 135 to Kodiak 100, and everything in between. Not just me, but half a dozen testers in trail shoes, road shoes, wide toe box shoes, and traditional toe box shoes.

They’re not minimalist insoles — they’re built for performance. We shaped the forefoot slightly wider so they play nice with wide toe box shoes, giving you a smooth fit right out of the box. They can be trimmed if needed, though honestly, we haven’t had to.

I ran the Kodiak 100 in Altra Lone Peaks, and the MFM insoles handled it all — heat, climbs, descents, and 30+ hours on the move — without compromising feel or stability. While the traditional shape differs visually from Altra's foot-shaped factory insoles, when you match the length properly, the functional difference is minimal.

The Bottom Line

Zero drop and arch support can coexist. You just need the right design philosophy — one that puts movement first and listens to real feedback from runners who live in their shoes.

Can’t wait to hear how they feel once you put some miles on them.
