Description

Just Say "No" to Cheap Foam Insoles Forget cushiony gimmicks - Ninjas orthotic arch support shoe inserts provide the solid, springy support that tackles common types of foot issues at their core. Ninjas are crafted from an ultra-durable, yet incredibly springy, polypropylene polymer for unmatched comfort and longevity. Avoid the usual pitfalls of cheap foams or gels - no wear and tear, no funky smells, and no soggy sweaty insoles. Ninjas are podiatrist developed and crafted in an orthotic laboratory right here in the USA. Forget those vague, one-size-fits-all ranges. We offer THIRTEEN PRECISION SIZES, so your feet get the perfect fit they deserve. Simply select your Samurai Insoles Ninjas size based on the size of shoe you will be wearing them in. Samurai Insoles Ninjas are the perfect choice for medium-fitting footwear with a removable insole like running shoes, casual sneakers, roomy dress shoes, basketball shoes, pickleball shoes, medium fitting boots and more. Are Samurai Insoles Ninjas a cushion? Are they soft and squishy? No. Samurai Insoles Ninjas are plastic arch supports with no foam or cushioning present. They must be placed underneath a shoes already present insole to be effective and comfortable. Are Samurai Insoles Ninjas a full length insole? No. Samurai Insoles Ninjas are 3/4 length, not a full length insole. They are designed to comfortably support the arch of the foot and not extend beyond the ball of the foot. Are Samurai Insoles Ninjas compatible with all shoes? No. Samurai Insoles Ninjas are only compatible with a shoe with a removable factory insole. My Samurai Insoles Ninjas seem small and/or narrow, is that correct? Samurai Insoles Ninjas are designed to comfortably support the arch of the foot. Despite appearing narrow for some, Ninjas are designed to provide comfortable arch support when placed under the shoe's removable insoles. I did not have immediate relief from wearing Samurai Insoles Ninjas, did I do it wrong? Your feet may need some time to get used to the support of Ninjas for maximum comfort. Start with wearing them an hour/day, and work your way up from there! For safety, we must recommend discontinuing use of Ninjas if pain is increased during use.

    • Review of many 3/4 length inserts for comfort and improvement over time.
Color: Purple Size: Mens 10-10.5/Womens 12-12.5
I have a lot of pain in my heel in the left foot. I desperately bought seven different pairs of shoe inserts on Amazon in an attempt to help decrease pain and heal the problem. Some pairs were very intrusive making walking nearly impossible. Other pairs were better. I am listing them in order from most uncomfortable the most comfortable and supportive. PCSsole 3/4 Orthotics, 330+ lbs Plantar Fasciitis 3/4 Length Insoles, Plantar Fasciitis 3/4 Length Insoles High Arch Supports Orthotic Insoles, Plantar Fasciitis Orthotic Shoe Insoles, QBK High Arch, Dr. Foot 3/4 Orthotics Shoe Insoles and Dr. Potter 3/4 Orthotic Insoles. I bought the 3/4 length instead of full length so I would still have plenty of space in my shoe for my toes to move around. I liked the Dr. Foot and the Dr. Potter inserts the most even though it took time to get used too. What I had trouble with in all the inserts there is a tendency for the shoe to tip when making left or right turning movements. I like to run trail trails and that would increase my chances of rolling a foot laterally causing me to fall and/or sprain an ankle. So I went back to Amazon and research more orthodontics. I came across Samurai Insoles Ninjas Plantar Fasciitis Relief Arch Support Shoe Insoles. They were purple and looked funny in the picture. I did not purchase these before because they looked flimsy to me. I bought them out of desperation. They actually slide in under your removable shoe padding (unlike the others I bought that went on top of the padding). I slid my foot into the shoe thinking this is just going to be a stupid idea, but it was far more comfortable than any of the other inserts I tried. The insert going under the foot padding actually made my foot more stable than the other inserts did. That was a plus! Then I noticed my foot did not hurt as much when I put weight on my heel. That was also a plus, but then I became concerned that it only felt better because I was not changing the pressure on my foot in a way that was going to give me the "correct" support I needed and I would in the long term just run into more problems (pun not intended). I decided to give the inserts a test. I went for a short walk and my heel was l little tender, but still much better than having no insert at all. I decided to mow my lawn. A small lawn that only took about 20 minutes. My foot actually felt better after mowing the lawn than it did before I started. Go figure? With the other inserts I would have had to sit and rest with my foot up for about an hour. Anyway, I have worn the inserts for a few days. My foot is slowly getting less and less painful. This was a relief in itself as I have had this pain in my foot for over 7 months with no sign of getting better. Hopefully, my foot well get better and I will be able to running the trails again. Right now these inserts are my best option. For that I give them 5 stars! ... show more

    • Immediate Relief!

My plantar fasciitis seemed to come out of nowhere. I tried a number of inserts to no avail. I was at the point while sitting my foot was throbbing in pain. I purchased the Samurai insoles. Popped them into my running shoes and instant relief. I never imagined they would be this effective. It’s been 4 days of using them so far. So thankful for this product. Sooo thankful ... show more

    • Cured my Plantar Pain
Color: Purple Size: Mens 6-6.5/Womens 8-8.5
About two weeks ago, I woke up with a horrific plantar fascitis pain the minute my heels touched the floor. I was in the worst pain and nothing seemed to help. I found an online post written by a podiatrist that explained the pain caused by plantar and how best to deal with it. The article recommended these insoles that I probably would not have chosen on my own. The price seems steep for the product and some people argue that "it's just a piece of plastic" which it seems to be when you open the package. Because I wasn't sure, I also purchased the product with better Amazon reviews and that one does not compare to the Ninja! I encourage you to try the product. My plantar is almost completely gone and the product is so great that I bought it for my wife and will buy it for my parents as well. I continue to use them under my sneaker insoles and they are just amazing the way they provide support while not losing the comfort of your own sneakers. I highly recommend this product to anyone suffering from Plantar or similar heel and foot arch pain. That little piece of plastic is the best darn piece of plastic you'll find. It's thick, durable, and curves in all the right places! Definitely get this awesome product! ... show more

    • PREVENTED full blown plantar fasciitis!!
Color: Purple Size: Mens 6-6.5/Womens 8-8.5
OMGOSH, I freakin’ LOVE Amazon (and no, I have no affiliation with them!!) I “almost always” find EXACTLY what I need with minimal effort. I have had the very UNfortunate experience of enduring the AWFUL, INTENSE PAIN that accompanies the heel of the foot from having plantar fasciitis. Twice. Almost three times- if it weren’t for these Samurai Insoles Ninja inserts. If you’ve never experienced plantar fasciitis then you won’t be able to fully comprehend how debilitating the stabbing pain can become- literally, physically it can bring you to a crawl. If you have had plantar fasciitis then you wouldn’t wish this kind of excruciating pain on your worst enemy - - OK…OK…maybe your “worst” enemy. Anywho, so having plantar fasciitis is horrible. The only positive, if you want to call it that, which comes to mind from having suffered through plantar fasciitis is that you can almost immediately recognize the onset of another bout, should you be unfortunate to get one. And that is precisely where these Samurai Insoles Ninja inserts helped in my case. I had, admittedly, forgotten my Podiatrists instructions to avoid walking barefoot, even inside my own home due to the lack of arch support my feet have, which is what triggers my feet issues (NOTE: different Dr’s & Podiatrist’s prescribe different treatments - some suggest wearing shoes all day long, while others recommend being barefooted, so follow whatever instructions your own Podiatrist or Healthcare advisor gives you), and within about a 2.5 weeks timeframe of going shoeless I woke up one morning and felt the ever so slight, but VERY familiar, pain of plantar fasciitis. Instantly I threw my shoes on and wore them the next two days ‘round the clock, hoping I could reverse, or at least halt, PF onset in its tracks before getting worse. Thankfully it didn’t seem to be getting worse, buuuut I also noticed that it wasn’t getting any better either. *My heel still hurt* I jumped on Amazon, ordered these Samurai Insoles Ninja inserts, IMMEDIATELY put them in my most commonly worn shoes (my ASICS), and wore them non-stop all waking hours. Still do. After putting these in my shoes and wearing them daily, along with doing exercises to strengthen my calves, I - literally - kid you not, felt NOTICEABLE improvement within TWO DAYS!! After following this routine (inserts + calf stretches) just shy of two weeks, I DID NOT HAVE ANY FEET PAIN, whatsoever, not even the slightest hint of PF, nor any other foot strain in either feet. In fact, even though all feet pain is gone, I have not removed these inserts. They remain in my shoes still today, three months after purchasing. If you fear you have plantar fasciitis, I STRONGLY recommend these Samurai Insoles Ninja inserts to help ease or reverse inflammation and pain. To speed up your recovery I also highly suggest the Vive Foot Rocker, which I used in conjunction with wearing these Samurai Ninja inserts to accelerate the healing process. These Ninja insole inserts saved me time and money that I’m absolutely certain would’ve been spent seeing my Podiatrist. #PF #PlantarFasciitis #FeetPain ... show more

    • Didn't work for me.
Color: Purple Size: Mens 12-12.5/Womens 14-14.5
Product did not work for me. Seems to be well constructed. I tried it with several different shoes but the high arch seemed to hit the front part of my heel instead of the arch. I did follow the break in as suggested. It caused more pain than it fixed. It make work for many individuals but not for me. ... show more

    • YES, they squeak. YES, they're too expensive. NO, they haven't helped(yet).
Color: Purple Size: Mens 10-10.5/Womens 12-12.5
Maybe I shouldn't give them such a low rating. I don't think I've ever rated anything on Amazon this low. BUT, these things are nothing but pieces of curvy plastic. NO WAY are they worth $35. If the price was somewhere around $10 I wouldn't be so disappointed. The arch isn't high enough for me. They're not uncomfortable, nor are they comfortable. Not quite sure if they're helping my Plantar Fasciitis at all. It's only been a week. I'm not sure they stay where they are supposed to under my foot. I am sure they make a lot of noise when I walk or shift my weight. I am looking into full insoles that seem to be more substantial for around the same price or cheaper. These feel like a gimmick to me. I see no reason to buy a 3/4 insert like these rather than a full insole. I don't know WHAT I was thinking when I put these in my cart and paid for them. I will keep them in my work shoes until I find something better or these flatten out. I will update my review if by some miracle these end up surprising me. For now I will keep looking for something that looks like it's worth the money. ... show more

    • They made a difference for me!!!
Color: Purple Size: Mens 8-8.5/Womens 10-10.5
Recently had total knee replacement and, following that, I was diagnosed with sciatica. These weren't perfect to solve my health issues, but certainly made a difference in my ability to get up and move. I could get through small walks with less pain and they certainly seemed very sturdy. My only wish was that they might not be quite so rigid. They do give good arch support and fit well in most of my shoes. Also, they are very easy to clean. ... show more
