That dull heel or arch pain you feel? It usually isn’t from “needing more padding.”
Foot pain often comes from overpronation — the excessive inward rolling of the foot that throws your whole body out of alignment. It’s one of the leading causes of plantar fasciitis, heel pain, and can even contribute to knee, hip, and back pain.
When the arch collapses with each step, the strain travels upward through your legs, stressing muscles and tendons that were never meant to absorb that load. Over time, this leads to pain that cushioning alone can’t fix.
That’s why Samurai Insoles Ninjas are designed to help control pronation, supporting your arches so your feet (and the rest of you) can move the way they’re meant to.

Simply slide Ninjas 3/4 length arch supports under your shoes' insoles and feel the difference.

Ninjas provide the solid, springy support that tackles plantar fasciitis pain at its core.

Samurai Insoles Ninjas give you solid arch support without the usual pitfalls of cheap gels or foams.

The Sumurai helps me to walk for exercise without pain from a neuroma in my foot!
Large factory worker here, ordered the Samurai Sumos for work boots. Great results!
First time purchasing innersoles and these are unreal. They were so nice I bought them thrice!
These insoles are amazing! I had stabbing pain in my right heel. I put them in my shoes and the pain went away. Then I worked on my feet for 8 hours with no pain.
I have had foot pain for several years. I have been to several specialist and PT to help rid myself of the pain and nothing helped. I took a chance and bought 3 pairs of your insoles. One pair for my work boots. One pair for my hunting boots and one pair for my gym shoes. After a week of wearing your product my feet are pain free. It’s amazing how fast your insoles work. I like them so much that I bought 3 more pairs for different shoes that I wear. I hope that the insoles continue working because I’m back to enjoying walking hunting and working out. I have no doubt that I will buying more as time goes on. Thank you for your great product.
I just turned 80. I have never had plantar fasciitis before. I have always loved to walk and jog barefoot on grass or the beach. It never caused me a problem over many years until this year in July. All of a sudden I had plantar fasciitis really bad. I read some advice that recommended stretching and using oan over the counter arch support. This same article said never, never walk barefoot! I ordered the ninjas, did the stretching and reluctantly stopped barefooting. It has worked. After about three months I am pain free. I will continue the routine indefinitely though I may eventually experiment with some limited barefoot activity.
These insoles are great . I can stay on my feet all day now .
My husband suffers from very sore feet and the Samurai insoles are the best thing we have found, we got the red insoles and now we are trying the new yellow. Thank you Samurai insoles.
I now have 3 pair of these. Along with my recovery sandals and two brands of orthotic shoes, the Samurai insoles help me to have a complete shoe wardrobe!
