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.

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 !

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.

Not for all shoes

I bought the recommended model. The arch was too high and the whole thing made my feet too high in the shoes. My heels, then, came out of my shoes when I walked.

Hi Marianne,

Thank you for reaching out to let us know and sorry to hear that the M100 was not a good fit for you. From what you described, it does sound like the T100 would have been a better fit as it is a thinner insole with a lower arch support. We are happy to help with a free exchange if you would like to give them a try. :)

We look forward to hearing from you!

Best Regards,
Drew
