Protalus M-100

Not an insole. Landing Gear. M stands for Maximum.

The T-100 introduced your foot to correct geometry. The M-100 is the full version — deeper walls, more of your foot guided through the correct motion sequence, through more of every step, under more load.

This is our flagship. In an independent 3D motion capture study (BioMechanica LLC, Dr. Martyn Shorten, Ph.D., 2019), 28 out of 31 people walked within correct mechanical range with the M-100. The T-100 gets 19. A standard foam insole gets 3.

One requirement: your footwear needs room. Boots, work shoes, and most shoes with removable insoles have it. If your shoes are snug with the T-100, you may be able to get away with the M-75.

Put them in your shoes. Take a step. Your body will tell you. 95 out of 100 say yes. The other 5 get every cent back.

Fantastic support!

Protalus are the best off the shelf inserts I've found and I have tried dozens and spent considerable money during the search; they run true to size and have done wonders for my arthritic knees and ankle.

Stable but flecible

The name Pro Talus really means that you have ankle motion. Most insoles stop foot motion. The innovative support give support but allows ankle motion in addition to the stability it provides. The new models with the U shaped support do just that. It takes a few days for your legs to adjust to the increased use of all the muscles in your legs that you use with this insole. It is not for everyone but it increases the ability to move and uses your muscles more efficiently as it does not try to stop you from moving your ankle

5 Stars

The Inserts are very comfortable and comfort my feet very well. It’d be nice if my foot was actually born this way. I should probably buy another couple pairs for my other pairs of sneakers. I would highly recommend this, especially if you have issues with collapsing arches in your feet or experience any type of foot pain this is the answer to comfort!

Excellent product and customer service

This product really does prevent the heel from leaning inward. Better alignment of ankles and up the chain of the hips and back. Will recommend them to others. Wish they had ones for sandals !

Hi Margaret,

Thanks for taking the time to share your experience! We're glad to hear you're enjoying them and will pass along the good word to others. :) Although we don't have a model designed for sandals, we did design a sandal with our insole technology built in! You can check them out at: https://protalus.com/pages/cascade

Best Regards,

Pain reduced

I’ve been having pain on the balls of my feet.

I walked a lot yesterday and realized my feet weren’t hurting and even my lower back pain was better.
