OrthoFlexx® was built to fix that. Our insoles were developed with orthopedic specialists to keep your arches lifted and your feet aligned, so the pressure that usually shoots into your heels, knees, and lower back finally starts to calm down.
You don’t have to change your shoes or your routine. Just slip them in and let them do the work for you.
Which condition are you dealing with?
Holds your heel in place and takes the pressure off the sore spot.
Supports your arch so your foot does not have to strain with every step.
Soaks up the shock from the ground so your foot feels less of it.
I highly recommend OrthoFlexx. My Podiatrists sold me some supports for my Plantar Fasciitis. They helped, but didn't eliminate it. I tried OrthoFlexx and within a couple of weeks the pain was almost gone. The customer service is the best I've seen from any company in many years. I can't say enough good things about them.
Gives your foot the arch support it is missing, without feeling strange to wear.
Stops your feet from rolling inward, which puts strain on your knees and hips.
Takes the pressure off the ball of your foot, which flat feet push too hard.
I have severe flat feet and plantar fasciitis. My doctor recommended shoe inserts and they worked fine. But I was looking for a bit more support and more comfort. I tried OrthoFlexx and they worked so well I’ve ordered more for all my shoes. Very comfortable and supportive.
Cushions the exact spot where your heel hits the ground first.
Keeps your heel from shifting around so it stays comfortable all day.
Pushes back gently with each step so your heel takes less of the hit.
A lot better compared to few other brands I used before. So comfortable soft cushioning with great arch support that best suit my high arch feet. Heel pain virtually gone.
Shifts your weight away from the sore bump with every step.
Takes pressure off the big toe joint so the bunion gets less strain with every step.
Spreads the load across your whole foot so the bump takes less pressure.
Since wearing OrthoFlexx I haven’t experienced any bunion pain. I’ve only been wearing them for a few weeks but can already notice my toes are pointing more straight forward and my bunions are less obvious
Lines up your feet and ankles so the strain does not travel up to your back.
Spreads your weight evenly so neither side of your body works harder than the other.
Helps you stand straighter, which takes the pressure off your lower back.
Best insoles I have ever used. I’ve tried Stepprs, CloudSole, Old Bones, Xstance, and a few others. I work 10-12 hours standing on concrete, and not only have they improved the pain in my feet significantly, my back and knee pain have improved as well.
