  • Feel the difference
Size: 12-12.5 Women/10-10.5 Men
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! ... show more

  • Cost, value and functionality
Size: 11-11.5 Women/9-9.5 Men
This is my second pair, which I use with my softball cleats. Maybe I shouldn't make this comment as I would hate to see their price changed ...but, between me and my insurance, paid over $600 for an orthotics pair (shown on the left - posted picture). The only difference between the two is that the SAMURAIs do not have the shoe insole included. I like to choose my own shoe-insoles, so for me it's an advantage. The SAMURAI inserts feel better, they fit perfectly and have helped reduce the pain remarkably. ... show more

  • The sizes are mislabeled
Size: 9-9.5 Women/7-7.5 Men
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. ... show more

  • Well, they work.
Size: 13-13.5 Women/11-11.5 Men
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? ... show more

  • My go to
Size: 10-10.5 Women/8-8.5 Men
I absolutely love my Samauri Ninja insoles. I love how I can still use the original insoles of the shoe and add arch support to them. The biggest benefit is adding these to dress shoes that are notorious to have flat insoles. The Ninja insoles make any dress shoe extremely comfortable.

  • PREVENTED full blown plantar fasciitis!!
Size: 8-8.5 Women/6-6.5 Men
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

  • Hard plastic insole inserts
Size: 8-8.5 Women/6-6.5 Men
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. ... show more
