Full description
Protalus M-100 Insoles — Maximum Alignment, Complete Control
Clinically Studied | Heavy-Duty Support | 90-Day Risk-Free Trial
Finally, Insoles Built for Maximum Correction
The Protalus M-100 is our full-power flagship insole, engineered to deliver maximum structural guidance and keep your entire body aligned from the ground up. With ultra-deep stabilizing walls that wrap your heel and midfoot, the M-100 actively corrects overpronation, absorbs high-impact forces, and holds up under the most demanding conditions — day after day.
Key Benefits
- Maximum Alignment — Deep, stabilizing walls wrap your heel and midfoot, guiding your foot through its ideal motion sequence from heel strike to toe-off
- Clinically Proven Results — In an independent 3D motion-capture study (BioMechanica LLC, 2019), 28 of 31 participants walked within the correct mechanical range with the M-100 — compared to just 3 of 31 with a standard foam insert
- Kinetic Chain Relief — Locking your heel into its proper vertical axis reduces the misalignments that cause knee, hip, and lower back discomfort.
- Heavy-Duty Construction — Built as a high-impact foundation that withstands demanding use, whether you're on a job site or logging miles on hard surfaces
- Full Overpronation Correction — Prevents the inward rolling of the ankle that leads to compensatory stress throughout the body.
- Full-Length Coverage — Maximum walls with approximately 7mm more depth than the T-100 for superior heel and midfoot control
Who Are the M-100 Insoles For?

- Wear boots, work shoes, or sneakers with a removable factory liner

- Want clinically studied results — not just cushioning

Fits in my AFO perfectly!
I had to order a half size larger shoe to fit my AFO (ankle foot orthotic). But I ordered these insoles in my “normal” size since my foot really hasn’t changed. The combo is working well for me, and the structure of these insoles will hold up over time better than the “custom” insole that came with the AFO.

I have used Protalus for years, but now are switching every shoe/boot I can to the M100. Fit and comfort are great and support is excellent.
