Weekly Innovation: 3-D Printed Fashion For Your Feet
This post is part of our Weekly Innovation series, in which we explore an interesting idea, design or product that you may not have heard of yet. Do you have an innovation to share? Use this quick form.
If Mary Huang could have it her way, she would digitize her world and make everything around her using a 3-D printer. But for right now, she's sticking to shoes.
Dr. Marlene Reid, a podiatrist, says our bodies are not meant to walk with our heels elevated three inches above the ground, or higher. It changes our biometrics, and our gait — we're "no longer walking normally," she says.
But that doesn't mean we shouldn't wear them; Reid says we just need to "wear them smartly."
So, according to Dr. Reid, remember:
- Don't wear the same heel height every day: Your Achilles tendon and the muscles will become contracted and shortened.
- Stretch out your Achilles tendon after you wear high heels.
- Platforms can negate some of the heel height.
- Know your foot type, and what components of the heel or shoe are important for your foot.
And she's doing it with a Brooklyn-based "part design label, part lab" company called Conintuum that says: "fashion should express how we live our digital lives." Huang designs the look of the shoe and the software that creates it to make it all possible.
She says a pair of shoes takes anywhere from 16 to 20 hours to print — that's eight to 10 hours per shoe. The shoes are made mostly from plastic, and thermoplastic polyurethane, a rubber-like material. They cost anywhere from $250 to $395 per pair.
But how practical are those heels? And any printed shoe, in general? Are they comfortable? Durable? Safe? Practical?
According to Huang's website, maybe not yet.
It describes her Daphne Shoe this way:
"This design is more of an art piece. While it is wearable with ribbons tied around the ankles, it is not suitable for day to day wear ... . This design is meant mainly as an exhibition or collector's piece, or for special events ... .This can also be purchased as a single shoe, for half the price."
Whether you can wear the Daphne heels or not, Dr. Marlene Reid thinks 3-D-printed shoes have a future.
"I think that's a really cool future for us," says Reid, a podiatrist and owner of Family Podiatry Center in Naperville, Ill. "The real potential is in creating custom shoes."
However, Reid is concerned about the materials that they are made out of, and that the shoes wouldn't be up to par with footwear standards.
What Reid says she's afraid of is "in its infancy, that the tendency would be to make a shoe of one material or limited material.
"Footwear has come such a long way in the development of materials and what they can provide for comfort and support," she says. "I think the technology has a lot of promise."
Huang thinks of her new-age, shoe-making process in the larger sense — how does (or can) it affect manufacturing?
"It's not going to replace how we traditionally manufacture things, but it gives you another option," she says.
Huang sees digital manufacturing as a potential way of changing how global supply chain works.
"The availability of cheap labor in the world is going to get more scarce," she says. "It's not that this would be a good process for everything we would want to design. It's a new process that has new benefits."
Huang says 3-D printing is a long-term technology: the goal is to learn and grow with it.
And now is only the beginning.
