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?

The M-100 is the right choice if you:
  • Need maximum alignment support and a heavy-duty platform
  • Wear boots, work shoes, or sneakers with a removable factory liner
  • Work on your feet in physically demanding environments

  • Want clinically studied results — not just cushioning
