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.

5.0 out of 5 stars I cannot wear my boots without these.
Reviewed in the United States on April 9, 2024
Size: 13-13.5 Women/11-11.5 MenVerified Purchase
I'm a skeptic, but I thought I'd take a chance one these hard plastic devices. It did not require me to cut. They needed to know my shoe size. Simple process. I suffer from plantar fasciitis. My left foot is severe. Walking after waking is like walking like a cripple. If I don't have crocs on im done.

Well trying this insert I had issue with my regular insole sliding on the insert when walking. But it seemed to quit or I quit noticing.
This product turned my ultra comfortable boots into uber comfortable boots. I can't wear them with out them. Not unless I want to be I'm pain.

I would recommend one for every pair.

4.0 out of 5 stars Let's Call Them Comfortably Uncomfortable
Reviewed in the United States on March 3, 2024
Size: 13-13.5 Women/11-11.5 MenVerified Purchase
Every shoe is different, and I have found no one iteration of any of these products works universally for all of my shoes. For instance, if you have insoles glued in, these obviously won't work. Also, some shoes have thin insoles and rely on the sole of the shoe for the bulk of shock absorption while other shoes offer a more substantially padded insole. Because these inserts are hard plastic, a well-padded insole will be considerably more comfortable. They will feel mildly uncomfortable, like you feel when you're stretching sore muscles, because that is what needs to happen to heal up; you need to stretch these soft tissues. But, I find that I can wear these all day, and my feet don't become fatigued. Also, if you spend any time on a ladder, the hard plastic shank does wonders for keeping feet from becoming fatigued. The 3/4-length design means that you don't have to try to cut them to fit your size of shoe. The little Velcro pads mean that the insole NEVER slips out of place. I now have two sets of these; one for a pair of Addidas athletic shoes and one for a pair of Columbia hiking shoes. Both are well suited to these insole inserts.

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?

5.0 out of 5 stars 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.

Size: 8-8.5 Women/6-6.5 MenVerified Purchase
I don’t see what the hype is about these innersoles because my heel hurts just as much pressing against this as it did without it in my shoe. I don’t feel any difference what so ever but I will keep them for another day and see if anything changes
UPDATE
Well this is day 2 and my foot still hurt when I woke up this morning but I wore the inner soles all day and by mid afternoon the pain was completely gone. I still can’t believe it because to look at these things you can’t imagine how they could do anything! I was all set on returning them. Do for now I’m going to keep wearing them and see if the pain stays away.
UPDATE Feb. 29
I’m still wearing them every day and the pain has never come back! They’re a keeper!

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.
