I take my feet seriously.

Which is why one December I found myself in an office, propping my legs on a chair while a tech startup CEO used an iPhone to scan my bare fingers from multiple angles. No, I wasn’t looking to become one A saucy victorian ankle flasher For lovers only. I was there to get a set of slippers groovea company that uses the iPhone’s Face ID camera and an artificial intelligence algorithm to create and print custom shoe inserts.

I was skeptical. Groov’s offering is personalization. People buy insoles because, let’s face it, even the most comfortable shoes don’t always fit. It’s worse if you have flat feet, plantar fasciitis, or a high arch. What makes Groov interesting is that you create a 3D model of your foot using technology that many people already have. The company then uses artificial intelligence to optimize the best surface for the individual foot. It’s similar to what a podiatrist does, but it doesn’t involve creating a plaster cast of your foot or his or her own 3D scanners.

Conversely, those $20 over-the-counter lotions offered by Dr. Scholl’s aren’t really made to You. Custom orthotics can be fitted by a podiatrist The cost is somewhere between $300 to $800may require a prescription, and may not be covered by insurance. (US healthcare! What fun!) iPhones are everywhere — sorry, no Android compatibility yet — and getting custom inserts from Groov doesn’t require a prescription. A pair of company inserts cost $150 and are also FSA/HSA eligible. In theory, this technique is used to obtain the exact input for it for you Provided in a cheaper and more convenient way.

On the other hand, products like Groov fall squarely into the world of Wild West wellness. These days, influencers sell everything from Questionable sanitary ware to Unapproved weight loss medicationspromising to fix everything that may happen to you. Some are backed (partly) by science, some are aimed at improving access to known treatments, and much of what is being sold is snake oil. But as far as health technology was concerned, Groov seemed harmless.

When I met Dan Cataldi, founder and CEO of Groov, he regaled me with an impassioned speech about how shoe fit has not evolved over the ages. Just as society has moved away from tailored clothing to fast fashion, shoes are being mass-produced in cookie cutters even though everyone’s feet are different. He says removable inserts are really the only way to make mass-produced shoes more comfortable. That’s why, when NBA players give their sneakers to fans, the first thing they do is take them off. they Custom insoles. Cataldi then proceeded to show me a video of athletes, including LeBron James, doing it.

There is a nugget of truth here. However, elite athletes are a superstitious bunch who will do anything to get the best results. I exercise a lot, but I’m not an elite athlete. I’m just a girl with wide feet and fallen arches, prone to calf strains and ill-fitting shoes. However, I thought Groov was a low-risk experiment in the world of optimization. I was going to put them in my sneakers at CES — a conference where I walk more than 10,000 steps every day. At best, my feet will hurt less. Worst case, I’ll end up getting a pair of insoles that I could have found cheaper at CVS.

As it turned out, last week was the culmination of a nearly two-year search for the perfect hiking shoe. In Vegas, I combined Groov entries with a new pair of shoes Recommended for AI browser New Balance 574 Core. Armed with a 15-pound backpack, I was traveling around raunchy casinos and show floors, testing… Pollutant catcher And investigation Sanitary ware that uses bodily fluids. And no one suspected that I was also experimenting with wearables for feet.

I regret to report that the results were inconclusive but It reminded me of the most harmful part of the Wild West: the placebo effect.

The day I took 18,000 steps, my feet still hurt. The pain was marginally less than on a similar day in October when I also logged nearly 18,000 steps trudging around Florence, Italy with my old car and Dr. Scholl’s inserts. But would the slight improvement matter if I still had to shift weight from one foot to the other when standing for 15 minutes between meetings, because having flat feet is really bad?

When I came back I tried both Virtual Insoles vs. Groov vs. Dr.Scholl’s. I jumped around. I walked. I ran errands. I stood for fifteen minutes doing nothing in the store. The arch support was definitely superior to the flat, support-less default settings. But it was Groov’s custom assignment better Of general inclusion? Yes. The arch support was more comfortable and the materials were of higher quality. It took a few thousand extra steps for me to start getting tired. But am I going to preach to every human with feet that $150 worth of phone-scanned custom inserts will do it? Change your life forever? no.

That’s the thing. There are perfectly good reasons to prefer either option, and I can convince myself of either. If I gave comfort the highest priority, my mind could jump through dozens of hoops to say Groov or Bust. If I value my wallet, I can convince myself that $20 CVS inserts are just as good. I know this because I spent 40 minutes having an existential crisis believing both, and overthinking myself into oblivion. The only definitive takeaway from an intense week of heavy walking is: which insole is better than no insole, and whichever I think is most effective will do. feel Best for me, regardless of whether that’s actually the case.

This is a prime example of what I call the “placebo technique” in the wellness field. the Placebo effect It refers to a scenario in which a fake medical treatment confers actual benefits – for example, in drug trials, one patient is given a real drug and another is given a sugar pill but somehow the latter notices an actual improvement. A few years ago I did a test Apollo Neuro – A wearable alarm device that claims to relieve stress. The science behind the marketing and behind the idea itself was questionable at best. However, sometimes it felt really good.

In this particular case, custom inserts are a real treat to improve the fit of the shoe and relieve foot pain. However, if you use buzzwords like artificial intelligence and a passionate CEO explains how using an iPhone democratizes personalization, you’re willing to believe that this is… better The solution is the traditional way. If you feel any comfort, you also tend to believe this The form of treatment works best too. This may or may not be true if you decide to test and compare different options.

To the average person, the placebo technique could look like this. You are fed many ads from influencers you like. Marketing includes buzzwords that are vaguely scientific or technological in nature, making it seem more trustworthy. You convince yourself to buy it, and you end up having a neutral to positive experience. You start thinking, “The thing I bought fits me, so it’s legit.” It doesn’t matter if 1,000 reviewers later debunk it as long as 20 of them say it changed their lives. You could have a hundred clinical papers on your way. Experts can talk about facts until they are blue in the face. If you think it works, it might actually work. And if it does not cause damageAnd no one can conclusively prove otherwise.

With Groov and many other health products, the main “harm” is the impact on your wallet. The problem is that they sit next to things that… He does It causes harm – and it is very difficult to make a wise judgment about which.

I would say that debunking health snake oil only requires common sense and media literacy. But the truth is that I often have to do first-hand experiments to find out what’s real, what’s fake, and what’s placebo. Part of my mission with Mohsen In 2026 is a demonstration of how I navigate the health Wild West, and I hope it encourages you to engage more critically the next time TikTok QVC promotes a miracle cure for whatever ails you.

Meanwhile, I have a sneaking suspicion that my search for the perfect walking shoe (or insole) will never end.
