Stop Fighting Flat Ground
Flat floors force your ankles to roll inward, throwing your knees, hips, and lower back out of alignment. The Protalus T-100 fixes the ground inside your shoe — instantly guiding your body into its ideal mechanical range of motion with every single step.- All-Day Energy — Guides your posture so your body stops working overtime
- Anti-Fatigue Cushioning — 7.5mm layer distributes impact energy and won't pack out
- Easy Fit — Drops right into your favorite sneakers or casual shoes with removable insoles
Proven by the Numbers
Most insoles only cushion you while standing still. Protalus actively guides your feet while you move. In independent 3D motion-capture testing, only 10% of people walked with proper alignment in standard shoes. With Protalus, 90% achieved successful, clinically validated alignment. Try risk-free for 90 days - If your body doesn't feel more aligned and less fatigued, send them back for a full refund, no questions asked.$64.95

Protalus M-100 Insoles — Maximum Alignment, Complete Control
Clinically Studied | Heavy-Duty Support | 90-Day Risk-Free TrialFinally, 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.
