Stop Fighting Flat Ground and Experience All-Day Comfort & Support

Flat floors force your ankles to roll inward, leading to overpronation and throwing your knees, hips, and lower back out of alignment. The Protalus T-100 orthotic insoles are expertly designed to fix the ground inside your shoe, instantly guiding your body into its ideal mechanical range of motion with every single step. These corrective shoe inserts provide crucial arch support and stability, transforming any footwear into a foundation for proper body alignment and reducing flat feet pain.

  • All-Day Energy — Guides your posture so your body stops working overtime, providing dynamic arch support and full-length comfort to reduce foot fatigue.
  • Anti-Fatigue Cushioning — A resilient 7.5mm layer effectively distributes impact energy, absorbs shock, and won't pack out, ensuring lasting comfort for all-day standing or walking.
  • Easy Fit — Drops right into your favorite sneakers, casual shoes, or even work boots with removable insoles, offering versatile and effective support.

Proven by the Numbers for Clinically Validated Alignment

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, demonstrating superior motion control and corrective benefits for pronation and flat feet.

Our full-length orthotic inserts feature a deep heel cup and firm yet flexible arch support, engineered to relieve foot pain and improve overall body alignment, providing lasting comfort and stability for those who experience overpronation or flat feet.

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. Experience the difference of premium arch support and all-day comfort for yourself.

These have kept me active!

The thinner version of the T-100 insoles have been a lifesaver for me. I have bad ankles and just had hip replacement. These are no-nonsense. I’ve actually thought about putting them in my slippers. Instead, I have a pair of indoor sneakers that I use with this insole. The insoles cushion my walk so that I’m able to walk confidently without pain.

Definitely worth every penny❣️

Comfort

I final found discovered an Insole that is a touch thinner for my just a little to snug tennis shoes. Don't get me wrong the T-100 elites are just as great in all my other shoes, I just needed something that was a little thinner so my toe wouldn't go to sleep after a 1/3 of my day.
