The perfect sneakers, custom leggings—we asked an expert if the 3D printing technology trend could really change the fitness world
Of all the crazy new advances in tech—new wearable technology that helps you break bad habits, computers you wear on your wrist (hello, Apple watch), even sports bras that combine wearable tech and fitness gear—hearing about 3D-printed wellness gadgets are one of those things that makes us feel like we’re living in the future. You’re telling me that you can use a printer to make actual, physical objects? It sounds like something straight out of sci-fi.
And while hearing about 3D-printed houses and makeup is cool, what we’re most interested in is how the new technology will change fitness. Imagine a world where you could 3D print the perfect pair of running shoes, custom molded to your foot, for example.
In fact, Nike, Brooks, and New Balance have all already dabbled in 3D-printed athletic shoes. And custom-printed shoe insoles will soon be on the market: SOLS ($125, sols.com) has you take measurements of your feet using their app, then prints you insoles in any one of a number of fabrics (leather for work shoes, something sweat-wicking for sneakers). Plus, they’re, a fraction of the cost of many orthotics. (Whether you wear insoles or not, you should definitely be stretching your feet post-workout.)
But footwear isn’t the only thing that can benefit from 3D printing. EXO-L is a company that's creating custom-made ankle braces, designed to keep athletes safer on the field or court. Other companies are offering molded-to-you mouth guards. You can even buy specially fitted, never-slip-out-again headphones ($200, nrml.com). All these products use 3D printing technology for ultra-customized end products. The benefits go way beyond personal comfort, though: 3D printing enables doctors to create comfortable, affordable prosthetics for people missing limbs too.

“3D-printed fitness gear has some serious pros, the most obvious of which is customization,” says Pieter Strikwerda, the co-CEO and founder of 3DPrinting.com. “But also it requires less production time from the idea to the finished product.”
Still, can 3D printed products really stand up to traditionally-made gear, especially higher-end products? Strikwerda says yes. “Printing techniques are getting better every day, and so are the materials being used,” he says. “Look at NASA—they’re using printing techniques to print metal parts for their engines, not only because it’s lighter and more efficient but also because those parts are stronger.” (This fitness equipment just looks like science fiction.)
That said, cautions Strikwerda, “the whole process of 3D modeling and scanning, choosing the right material, and so on is still really complex. It’s not a plug-and-play machine yet.” So we’re not quite at the point where we’ll be able to print out a spare pair of running shoes or fit-like-a-glove leggings from the comfort of our own homes. But until we get there, at least we can finally get our hands on ear buds that won’t slip out during our workout, and insoles that make our run feel better without breaking the bank. That feels pretty futuristic to us.
