The Explorer™ (Level 0)
The Explorer™ (Level 0)
The Explorer™ (Level 0) - Development & Maintenance Support
For children with healthy alignment, or those transitioning from corrective support.
What It Helps With:
• Healthy foot and ankle development
• Maintaining alignment as children grow
• Post-correction maintenance and support
How It Works:
Unlike our corrective levels, The Explorer does not contain a corrective wedge. Instead, it provides gentle arch support and a deep heel seat to help promote healthy foot positioning and everyday comfort.
Key Features:
• No corrective component
• Deep heel cup for positioning and stability
• Gentle, soft density arch support
• Designed for healthy development and maintenance
Important Fit Note:
The Explorer is our most cushioned insole, designed for healthy foot development and everyday comfort.
For the best fit, use in shoes with removable insoles. Remove the existing insole and replace it with your NUKIX insole. If the shoe does not have a removable insole, sizing up by half a size may improve comfort.

I requested these kid insoles for use in my son's rainboots, which are line with only a thin layer of padding. They arrived within two days of shipping and came in their own box, no damage noted. They are pretty flexible and offer more support in the arch and heel. The inserts are easily trimmable to achieve a custom size.
With all the rain we have had in the last few weeks, I am glad to have found these. They went in easily and the bottoms (in combination with the inside of the boots) are non-slip, ensuring a secure footing. My son says his feet feel better when wearing the boots now compared to before (when the padding would slip out every time he took his foot out). This is a great product. No complaints, except for maybe the price -- at $36, these insoles are more expensive than the actual boots we're using them in. Name brand pairs can be found online and pharmacies for under $20.
These insoles are really well-made and soft, with good arch support. I’m an adult size 8, and these are also perfect for me!
I got these insoles for my little one for his comfort and posture. The soft orthotic support is great as it helps keep his feet and ankles aligned. The material feels good quality and they are easy to slip into his shoes without any fuss. However, I feel that they are a bit on the pricey side for something kids will eventually outgrow. While they do deliver on comfort and support it might not feel like the best value for parents on a tight budget. Overall, it is decent for foot support and comfort.
These orthotic insoles are intended for children. I ordered this in a size 5.5 to 6.5. Sizing seems accurate. As an adult who wears orthotic insoles every single day, I find the support in these insoles to be lacking. The arch support is quite flexible, so under any kind of weight, it flattens out. It does not stay firmly upright to support the arch properly. The heel cup is a nice size and does ensure the child's foot remains in its proper location. With that being said, it is a pretty good insole for children. Perhaps the sturdiness of the arch support is not as necessary for children. I would want more support in my insole, so for me this would not be a great product.
Genuinely useful review, much appreciated — and thank you for confirming the sizing runs true, which helps other parents more than you'd think.
On the support: these are made for a child's body weight, so under an adult's load the arch will compress. That's the design rather than a defect. The Explorer is also our Level 0, meaning no corrective wedge — our Builder and Champion are considerably firmer, though still built for children's feet. We hope that's useful if you're considering moving to a corrective insole in the future.
Really nice insoles! Fit perfectly in the shoes. Definitely seemed to bring some extra comfort. Nice quality and build. I'm really happy with this!
I gave these insoles a try hoping they'd help with daily comfort, and while they're soft and cushiony, they don’t offer quite enough arch support, especially if you have flat feet. They’re fine for short walks or casual wear, but after a few hours, I could feel the lack of proper support.
They're easy to slip into most shoes and feel decent at first, but if you need serious arch support, these might not do the trick. Not bad overall, just not ideal for every foot type.
Thank you for taking the time, and you've put your finger on something important. The Explorer is our Level 0 — cushioning and everyday support, with no corrective wedge at all. For flat feet we built The Champion (Level 3), which uses a 6–7° wedge and a much firmer structure.
That distinction wasn't clear enough where you bought these, and that's on us. Our Foot Type Guide now matches each foot type to the right level before you order.
NUKIX Arch Development Insole for Kids, Soft Orthotic Support for Ideal Foot & Ankle Development • Size 5.5-6.5 (youth)
According to my 9 yo grandson these insoles offer a decent amount of support and make his footwear more comfortable to wear. He is used to using orthotics so he didn't have a wearing in period.
The insoles appear to be well made. The arch support seems to be quite firm when gripped. It may not be as firm if worn by a heavier person as there is some give. Best to test if unsure. This shouldn't be a problem with a 30 day "any reason" return policy. There is room to customize the fit further by trimming the footbed.
We have used Nukix products before and have, on the whole, found them to be quite effective and durable. The pricepoint is supported by the overall quality of the product.
Please note that the insoles alter the fit/tightness of the footwear. Any original insoles should be removed before fitting the supports.
Try some.
Got these for my wife to use in her daily work shoes. She says they are quite comfortable, and provide good support for her feet. Construction quality is good, and they have held up quite well so far.
These are very comfortable arch supports. I find others to be hard feeling and painful. Not these! I use them in my skates and they are perfect!
I ordered these insoles for my own sneakers and they are excellent. I'm a grown woman but I have small feet and can fit a kid's size 4 shoes (which is the same as a women's size 6-6.5). These insoles really help my flat feet. They are made of a cushioning material which is made of memory foam and it is very comfortable. There are grips on the bottom which ensure that the insoles stay in place without sliding forward into your boot or shoe. There are indicator lines that tell you where you can cut the insoles at the top if you need them to be smaller to fit into your shoes. This was very easy to do. The first few days of wearing these insoles felt strange, but after breaking them in, they were very comfortable.
Gave it to my son and tried these insoles. Unlike other supports that feel rigid and uncomfortable, these have a soft, cushioned design that actually makes him want to wear them. The arch support is subtle yet effective, providing just the right amount of guidance for his developing feet.
I purchased multiple products from this vendor and I’m happy with all of them. They produce top quality insoles that last for a long while. Highly recommend trying them out.
I ordered the 5.5 to 6.5 Youth Size insoles and they fit into Asics Juniors' GEL-Noosa Tri 16 GS (Grade School) Running Shoe Size 5.5 without any trimming required.
There was no extra material in the toe area so if the shoes were sized 6.5 then the insoles may have been a tad short.
The padded support is better than the flat insoles that come with any pair of shoes. But it isn't as sturdy as quality Orthotics or custom Orthotics. It does squish down a bit as this pair of insoles has a soft padding.
The padding does give it some comfort and some shape and support.
My daughter is in between sizes right now and has issues with foot pain due to her arches being quite flat, and after only a few days has been telling me how comfortable her feet are&how much of a difference it's making in her being able to enjoy activities we love like going on longer walks etc.
Hopefully they will hold up well to an active child's wear and tear, they seem well made but not as structured as some adult insoles I have.
Kids' insoles are often overlooked, and these genuinely come to the rescue. They slip easily and work well in winter boots and also sneakers. They work particularly well for Chuck Taylors or any other shoes with minimal padding on the insoles.
