Feel the difference

Reviewed in the United States on May 22, 2024

Size: 12-12.5 Women/10-10.5 MenVerified Purchase

These are much more comfortable out of the gate than a lot of other options I've tried. They go in easy, have ample support, and are well built quality. I have felt a noticeable difference since using them and my feet have adapted fairly quickly to the new support. The difference was immediate in feeling the way my feet SHOULD be compared to how they were. I replaced my stock insole with one that had an added heel cushion for my specific circumstance and they fit perfect with it!

PREVENTED full blown plantar fasciitis!!

Reviewed in the United States on September 30, 2021

Size: 8-8.5 Women/6-6.5 MenVerified Purchase

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.

The sizes are mislabeled

Reviewed in the United States on April 5, 2024

Size: 9-9.5 Women/7-7.5 MenVerified Purchase

I've been struggling and struggling to find 3/4 length arch supports. The prior Ninja's never worked. I finally realized that they might be too small. I just ordered a size larger. Wow! They feel so much better...and then I realized that the Ninja yellow sticker on the bottom was intentionally covering the European shoe size. Um, why did Ninja sell me a EU 37 for a size 8.5 Women's? I have reliably been a EU 39. So, now that I've ordered Ninja women's size 9-9.5, I get an EU 38. I wonder what it takes to get an EU 39? Regardless, getting the larger size is soo much more comfortable and hopefully will alleviate the foot cramps I get when wearing the too small-sized supports in my flat ankle boots.

Well, they work.

Reviewed in the United States on March 23, 2024

Size: 13-13.5 Women/11-11.5 MenVerified Purchase

So yeah, as I said in the title, they do work, that's the plus. The downside is that we all own more than one pair of shoes. Provided with the inserts are two sticky pads to hold them in place, thanks to this I am unable to move them from one pair to another without wearing out the sticky pads. So forget about the pads I did. It turns out that even without the pads the inserts are managing to stay in place anyway. They're a bit on the uncomfortable side but hey, you've gotta do what you've gotta do. Maybe a different brand would be better with a softer sole?

I have flat feet, especially my left foot. Over the past several months, it had gotten so bad that my left heel had completely locked up on me. Massages and heat just weren’t doing the job. So I took a chance on these podiatrist- designed supports. They are absolutely magnificent! My ankle stopped bothering me about two minutes after I had put these into my shoes. Congratulations for making such a great product available to all of us with sore

Hard plastic insole inserts

Reviewed in the United States on October 26, 2023

Size: 8-8.5 Women/6-6.5 MenVerified Purchase

No no no. These killed my feet like no other. I have severe pain in my right foot due to plantar fascitis and whatever else is going on. The expensive prescription orthotics also killed my foot and made pain worse.
These can go under the foam insert but if that has any arch support that's going to cause the foot to hurt due to higher arch support than needed.
I gave these my best try but by the third day I was done. The pain in my foot was worse than when I started. It should mellow by the third day not worsen. If these were padded with a soft foam I think they'd be better, but as is they are like walking on a hard surface and for painful feet, that's not good.
I would never purchase these again, the cushy insoles always help my right foot for awhile they just break down fast. These, I couldn't even start them long enough.
If hard surfaces hurt your feet more I'd say these are not for you. If your feet are not bothered by hard surfaces, they may work for you. These types of products are subjective to the person. Just know they're super hard and not cushy at all. I returned mine after a few days.

Comfortable, flexible and fair priced

Reviewed in Canada on May 24, 2024

Size: 8-8.5 Women/6-6.5 MenVerified Purchase

I lost my custom orthotics about a year ago and was suffering terribly with plantar fasciitis. My daughter bought these orthotics for my granddaughter to use especially in her soccer shoes. She no longer complains of painful feet when she gets off the pitch. So I gave them a try. I’ve been wearing them for over a week now and they are very comfortable to wear! I just lift the heel portion of the insole and insert the orthotics. They allow my foot and ankle to move like they were intended to and yet they provide the necessary arch support without paying $500 for custom orthotics. Will definitely buy these again!!!

I bought these for my heel spur but it was such very hard plastic, that it only made my heel feel worse, so i returned it. After reading it properly i made the mistake of thinking that heel spur and fasciitis were the same and they are not. So id suggest to anyone wirh foot issues to really find out what your foot issues are before buying this product

I have worn them now for one week and the constant pain is virtually non-existent. I still get the occasional twinge or muscle spasms but overall I am impressed. I will be hopefully completely convinced once I try them out in a long walk and/or hike. However, one week in as a busy pre-school teacher, I am pleased.
