The best for my weak ankles.

I used them a few years ago then stopped because I thought the orthopedic sneekers would be enough to support my "rolling" ankle condition and lower back pain. I was wrong.

I recently purchased more inserts and am slowly adapting to them once again. Glad I did. The support is quite noticeable.

Not right for me

Had high hopes but after wearing for a week I developed hip pain. Put old insoles back in and pain is almost gone. Unfortunate.

Hi John,

We appreciate you taking the time share your experience with the M100 insole and are sorry to hear that they are not working out well for you. We do see that you also ordered the T100 style, has that been a better fit for you? If so, we can help exchange that M100 for another pair of the T100 for you. :)

We look forward to hearing from you!

Best Regards,
Drew

Plantar Fascia pain

They are working a bit better than the Superfeet I have tried. Still not free of pain in my heel, but not sure it’s a result of the Protalus insoles.

Hi Bart,

Thank you for taking the time to share your experience so far. :) Here are some recommendations that may help you in the process of wearing your new insoles.

  • There can be an adjustment period for your body to adjust to proper alignment. It may take your body a couple weeks to adjust to the new alignment. Customers who have worn our insoles for at least 30 days have achieved the best results.

  • Improved alignment will change and may distribute new forces to your muscles, soft tissues, joints and tendons. When possible, we recommend wearing the insoles for 1-2 hours the first day, 2-3 hours the second day, and 3-4 hours the third day while continuing to increase wear by 1-2 hour increments until a full day is reached.

  • Make sure to remove the factory insole from your shoes before inserting your Protalus insoles. Our insoles need to lay flat in the shoes to work correctly.

  • Try them in different shoes. Sometimes shoes can significantly affect the performance of our insoles.

  • Tie and re-tie your shoes throughout the day. Hot spots can happen because your foot is moving out of sync with your shoe. Tying and re-tying your shoes unite your feet, shoes and our insoles, so they can move as one.

  • Lastly, we recommend the stretches listed at https://www.protalus.com/pages/stretches if possible. This especially helps in the process of alignment so that your body adjusts properly.

We certainly hope some of these can help out!

Best Regards,
Drew

New generation is even better

I've been wearing Protalus insoles for nearly ten years. I always put them in my running shoes, and shoes where the insoles can come out relatively easily. The new generation M-100 is definitely superior to the older generation, where I felt some ridges on the bottom of my feet and toes. Not so with the latest design. I highly recommend this new M-100.
