Looking for a stronger stimulation and more powerful impact on the proprioceptive system while you’re wearing shoes? Put a Naboso textured insole in your Xero Shoes!

“Naboso” means “barefoot” in Czech, and the Naboso technology and Naboso insoles were developed by Dr. Emily Splichal, a podiatrist committed to natural movement and the benefits barefoot.

My (Steven Sashen) personal experience with Naboso was, frankly, surprising. For years, I’ve tried various “stimulating” insoles and never noticed anything other than how uncomfortable they were.

So it was with great trepidation that I tried the Naboso proprioceptive insoles. After all, didn’t want to call Emily and tell her that they, like all the insoles before them, had no effect!

I didn’t have to make that call because I was shocked by the effect… 

I trimmed them to fit my Prio shoes, replaced the insoles in my Prio with the Nabosos, and wore the insoles for a few hours — I could FEEL them, but they weren’t too uncomfortable. When I took them off is when the surprise hit me.

As I walked around barefoot, I could feel my feet engaging more, gripping more. They felt stronger and more active. My calves, too, felt like they were spring-loaded. I had more bounce in my step.

I keep the Naboso insoles in my Prio for every activity — for walking, running, hiking, working out. Every now and then, though, I give my feet and my nervous system a “rest” — either by wearing a different shoe, or taking out the Naboso insoles.

Some people wear thin socks when they want a bit less stimulation.

Nice addition

I like the Naboso insoles, I put them in my Aptos to help them fit better; I have low-volume feet, and need to add insoles to most of my Xero shoes to get the best fit; I also like the additional foot stimulation of the Nabosos.

These insoles are amazing. They provide incredible stimulation to your footbed and are super easy to cut to fit, for the perfect size!

Love these insoles...I have neuropathy and they help a lot.

Ready for a little recovery at the end of the day

Shortly after receiving my Activation Insoles that I put in my Xero Aptos shoes, my puppy got at my last favorite holdout pair of footwear from before my transition to barefoot (mostly Xero) shoes - a pair of Bison leather driving moccasins from Duluth Trading Co. He did very little damage to the leather, but got the insoles out and destroyed those. I like the moccasins and was able to do a little leather repair. So, I removed the inserts under the insoles (which did give them a slight heel drop and some unnecessary rigidity) and I threw out the damaged insoles. I bought a pair of the Naboso Performance insoles from the Xero shoes site, figuring that they would give me the benefits I like from the Activation Insoles and the socks, but a little less stimulation might be a little more comfortable at the times I usually would wear the moccasins (mostly around the house). I now have a truly "minimalist" pair of slippers that are more flexible than they were, have no heel drop, and that will still provide some of the benefits of better circulation, helping with better postural alignment, and muscle release. I've gotten used to the Naboso socks and the Activation Insoles, so when I tried these on after cutting them to fit, I could notice less stimulation, but I also could feel it enough that I believe there will be benefit. And I will wear my Xero Aptos with the Activation Insoles after activity when I truly could benefit from a recovery shoe.

Naboso Activation Insoles Improved my already awesome Xero Aptos shoes!!!

I chose the Naboso Activation Insoles, as I have owned the Recovery Socks for a few months, so I am used to the texture. I cut them to match the insoles of my Xero Aptos shoes, as this choice serves two purposes for me. The first is to have the Naboso texture, which I like to stimulate the nerves of my feet. I feel the benefits of better sensation and blood flow. Also, since I live in Wisconsin, I'm only barefoot outdoors for some of the year; and I like that wearing the Naboso texture in winter helps me to stay accustomed to walking on different surfaces barefoot instead of being really sensitive and having to "re-adapt" again in spring/summer. The second purpose is that I always felt that my Aptos shoes fit a higher-volume foot and I had extra room height-wise (if that makes sense). Adding the Naboso insole helped close that gap and makes these shoes fit my foot height a little better - especially since I prefer not to wear socks in my slip-ons anyway. I like the insoles much better than the socks simply because the socks are compression socks and I never much liked the feeling of my feet and toes being squeezed into something that's tight. The Naboso texture and it's benefits always made it worth it to wear the socks for an hour or so, but I find standing on the insoles much more comfortable and I will probably use them more often and/or for longer periods of time.

Game changers!

These soles have enabled me to feel how my step wasn’t the same bilaterally. I didn’t even know. 10/10 would recommend!

These Are New to me yet...

I cut these inserts to fit into my new Alpine boots, both to make them fit a little snugger, and to give some activation while wearing the boots....which I have not done a lot of yet, since the snow stopped once I received my boots 🙂 These Naboso inserts are much more intense than the ones in the Naboso Xero sandals, but I will be wearing socks with my boots, so they won't feel as intense as the sandals do against the skin of my feet. I am about to order another set of these Naboso inserts and cut them to fit any other shoes that I decide I want to wear them in, such as the Cassie, and maybe try them in my Speed Force shoes as well. I like my boots a little bigger than my regular shoes so I need two different insoles to fit my shoe sizing. Blessings, Pamela

So far, so good

The Best

I’m so encouraged by these insoles. To go on each day feeling the same old fatigue in my feet and then… I find the Duo insoles and voila! A really great, interesting product that stimulates my feet in a gentle way while walking - how convenient. Well done Xero!
