When we think of wearable technologies, ballet shoes aren’t the first devices that come to mind. In fact, the E-Traces pointé shoes by [Lesia Trubat] may be the first ever “connected ballet shoe.” This project captures the movement and pressure of the dancer’s feet and provides this data to a phone over Bluetooth.
The shoes are based on the Lilypad Arduino clone, which is designed for sewing into wearables. It appears that 3 force sensitive resistors are used as analog pressure sensors, measuring the force applied on the ground by the dancer’s feet. A Lilypad Accelerometer measures the acceleration of the feet.
This data is combined in an app running on an iPhone, which allows the dancer to “draw” patterns based on their dance movements. This creates a video of the motion based on the dance performed, and also collects data that can be used to analyze the dance movements after the fact.
While these shoes are focused on ballet, [Lesia] points out that the same technique could be extended to other forms of dance for both training and visualization purposes.
Winter may be coming to a close but that doesn’t mean that feet are free from being cold. Sure, socks or slippers may help a little, or you can even turn up the heat in your home but none of those options are as fun or as dangerous as [Colin Furze’s] solution. He has come up with some crazy DIY heated slippers.
Sure, there’s battery powered heated slippers or even ones you can microwave to heat up but those are wicked boring. These puppies are actually gas powered and more resemble a small portable camping stove than any sort of footwear. Under each slipper is a custom-made burning chamber inside which is a small burner. Each slipper is supplied a constant flow of fuel from its own on-board gas can. Warming your feet couldn’t be easier, just turn on the gas and light the burner with a match.
It goes without saying but we should reiterate… Don’t try this at home! What you can try is watching the video of these slippers after the break.
[Colin Furze] is not new to having his projects on Hackaday. For more of his flame-based projects, check out his Pyro Gloves. And of course, who could forget these amazing retractable Wolverine Claws.

With the world’s first hoverboard being shown a few days ago, we’re on the verge of the fabulous world of tomorrow from Back to the Future. Hoverboards are cool, but there’s a wealth of other cool technology from the far-off year of 2015: Mr. Fusions, inflatable pizza, Dustbusters, and of course, Nikes with power laces. [Hunter] just built them, and with the right shoes, to boot.
[Hunter] is using the BttF-inspired Nike Air Mag shoes for this build, along with a few bits of electronics – an Arduino pro mini, a force sensing resistor, and a motor. The build began by carving out a notch in the back of the shoe for the electronics. A small bit of fishing line goes around the shoe, providing the power behind the power laces.
A force sensitive resistor under the heel of the insole tells the microcontroller when a foot is inside the shoe, and a rotary encoder on the motor shaft makes sure all the power lace cycles are the same. It’s not quite the same as the shoe seen on screen – the lower laces can’t be replicated and it’s certainly not as fast as the BttF shoes, but it does work, and as far as shoelaces are concerned, they work well.

We’re hoping that whomever came up with the idea of integrating LEDs into children’s shoes is kicking back on a beach somewhere living off the residuals of the idea. We see those things everywhere. Now the real question is, if you grew up with LEDs in your shoes do you expect cooler light up kicks as you age? [Becky Stern] must think so and that’s why she’s showing off Adafruit’s addressable LED strip shoe project called Firewalker.
This is prototype rather than product, so you can see the Arduino compatible Flora board on the ankle of the lit shoe above. There’s also a battery pack hitching a ride on the laces. But those worried about that fashion faux pas can work on a more finished driver that straps to your calf, or can be integrated in the insole.
Lighting patterns are set off by Velostat, a pressure-sensitive conductive sheet that goes in the heel of the insole. The Flora board measures the resistance, triggering a light show (embedded below) when it drops. Now we just need someone to integrate a power generator based on your movement.

Even though giant multouch display tables have been around for a few years now we have yet to see them being used in the wild. While the barrier to entry for a Microsoft Surface is very high, one of the biggest problems in implementing a touch table is one of interaction; how exactly should the display interpret multiple commands from multiple users? [Stephan], [Christian], and [Patrick] came up with an interesting solution to sorting out who is touching where by having a computer look at shoes.
The system uses a Kinect mounted on the edge of a table to extract users from the depth images. From there, interaction on the display can be pinned to a specific user based on hand and arm orientation. As an added bonus the computer can also recognize users from their shoes. If a user is wearing a pair of shoes the computer recognizes, they’ll just walk up to the table and the software will recognize them.

Motorized treads as a replacement for the heel of your shoe? Okay, remember how The Jetsons had moving sidewalks everywhere so you wouldn’t have to walk at all? Well, there’s a much more efficient way to do it and Treadway Mobility seems to have figured it out. In the video after the break you can see several of their prototype units zipping the wearer around quite happily. We think the best part is that with the tread locked in place you can stand and walk like normal, assuming you don’t feel like you have a block of concrete attached to each foot. Maybe the real question is which is more geeky, this or the power lace shoes?

Back to the Future Part 2 provided a glimpse of a future that included hover boards and holographic advertisements. But you don’t have to wait until 2015 to get your hands on at least some of the technology. [Blake Bevin] has produced a pair of shoes with power laces as seen in the film. Of course present day technology doesn’t allow him to make the mechanical parts disappear so you’ll have to deal with two servo motors and an Arduino hanging off of your heels. But hey, at least you won’t have to tie your own shoes like some 20th century peasant. No word on using these for a little theme music as you walk around but maybe that’s something from the more distant future.
