CAD Up Some Shoes, But Don’t Start From Scratch

March 3, 2022 by 13 Comments

Nothing helps a project get off the ground better than a good set of resources, and that’s what led [DaveMakesStuff] to release his Digital Shoe Design Kit, which is a set of 3D models ready to customize into a basic running shoe.

This is exactly what is needed for people who are interested in designing a custom shoe, but perhaps not interested in modeling every element entirely from scratch. [DaveMakesStuff]’s resources allows one to mix outsoles, midsoles, uppers, and other basic shoe elements into a finished model, ready to be resized or even 3D printed if desired. The files are all in stl format, but resizing stl files is trivial, and more advanced editing is possible with mesh sculpting programs like Blender.

If the gears in your head are starting to turn and you are wondering whether it is feasible to 3D scan your feet for some experiments in DIY custom footwear, take a few minutes and read up on 3D scanning and what to expect from the process to hit the ground running.

3D Printed Shoes Make Bigfoot Tracks

March 2, 2022 by 18 Comments

[Stephan Henrich] is probably going to set off a wave of bigfoot sightings if his new shoe, the Cryptide sneaker takes off. The shoe is completely 3D printed in flexible TPE using a laser sintering printer from Sintratec. The shoe takes a name from cryptozoology and, in fact, would leave a puzzling footprint due to its articulated toes and scaly-looking sole.

Judging from the look of the sole, it should be pretty cushy and we presume if you were 3D printing these, you’d scan or precisely measure the intended foot for a perfect fit. You can see a video about the shoe below.

3D Printed Sneakers Are Now A Thing

October 5, 2018 by 20 Comments

Shoes may seem simple at face value, but are actually rather complex. To create a comfortable shoe that can handle a full day of wear without causing blisters, as well as deal with the stresses of running and jumping and so on, is quite difficult. Is it possible to create a shoe that can handle all that, using a 3D printer?

[RCLifeOn] discovered these sneakers by [Recreus] on Thingiverse, and decided to have a go printing them at home. While [Recreus] recommend printing the shoes in their Filaflex material, for this build, one shoe was printed in thermoplastic polyurethane, the other in Ninjaflex. As two filaments that are both commonly known to be pliable and flexible, the difference in the final parts is actually quite significant. The Ninjaflex shoe is significantly more flexible and cushions the foot better, while the rigidity of the TPU shoe is better for ankle support.

Our host then takes the shoes on a long run through the woods, battling dirt, mud, and other undesirables. Both shoes hold up against the abuse, although [RCLifeOn] notes that the Ninjaflex shoe is much more comfortable and forgiving for longer duration wear.

We’ve seen other 3D printed shoe hacks before, too – like these nifty shoelace locks.

Self-lacing LEGO shoe

Self-Lacing LEGO Power Shoe

February 1, 2017 by 12 Comments

Here’s a blast from the past, or future, reminiscent of the self-lacing shoes from Back to the Future Part II. [Vimal Patel] made his own self-lacing shoe using LEGO “bolted” to the shoe’s sole. We think these are cooler than the movie version since we get to see the mechanism in action, urging it on as the motor gets loaded down pulling the laces for that last little bit of tightness.

The electronics are all LEGO’s Power Functions parts. A Dremel was used to make holes in the soles to hot glue LEGO pieces for four attachment points. The attachment points are permanent but the rest can be easily removed. In case you want to look them up or make your own, he’s using the using the 8878 rechargeable LiPo battery box, the 88003 L-motor, the 8884 IR receiver, and the 8885 IR remote control. That’s right, these shoes are laced up under command of an IR remote control, well, provided the battery box is powered on. There’s a 1:24 worm gear reduction to get the needed torque.

This was a quick build for [Patel], done over two afternoons. He initially tried with the winding axle behind the heel but that didn’t work well so he moved the axle adjacent to the laces instead, which works great as you can see in the video after the break.

Weather-aware Shoe Rack Helps You Get Ready For The Day

August 27, 2016 by 8 Comments

If you’re anything like us, your complete shoe collection consists of a pair of work boots and a pair of ratty sneakers that need to wait until the next household haz-mat day to be retired. But some people have a thing for shoes, and knowing which pair is suitable for the weather on any given day is such a bother. And that’s the rationale behind this Raspberry Pi-driven weather-enabled shoe rack.

The rack itself is [zealen]’s first woodworking project, and for a serious shoeaholic it’s probably too small by an order of magnitude. But for proof of principle it does just fine. The rack holds six pairs, each with an LED to light it up. A PIR sensor on the top triggers the Raspberry Pi to light up a particular pair based on the weather, which we assume is scraped off the web somehow. [zealen] admits that the fit and finish leave a bit to be desired, but for a first Rasp Pi project, it’s pretty accomplished. There’s plenty of room for improvement, of course – RFID tags in the shoes to allow them to be placed anywhere in the rack springs to mind.

Hackaday Prize Entry: DIY Foot Orthotics

July 1, 2016 by 7 Comments

What does your gait look like to your foot? During which part of your gait is the ball of your feet experiencing the most pressure? Is there something wrong with it? Can you fix it by adding or removing material from a custom insole? All these answers can be had with an expensive system and a visit to a podiatrist, but if [Charles Fried] succeeds you can build a similar system at home. 

The device works by having an array of pressure sensors on a flat insole inside of a shoe. When the patient walks, the device streams the data to a computer which logs it. The computer then produces a heat map of the person’s step. The computer also produces a very useful visualization called a gait line. This enables the orthotist to specify or make the correct orthotic.

[Charles]’s version of this has another advantage over the professional versions. His will be able to stream wirelessly to a data logger. This means you can wear the sensor around for a while and get a much more realistic picture of your gait. Like flossing right before the dentist, many people consciously think about their gait while at the foot doctor; this affects the result.

He currently has a prototype working. He’s not sure how long his pressure sensors will last in the current construction, and he’s put wireless logging on hold for now. However, the project is interesting and we can’t wait to see if [Charles] can meet all his design goals.

Heated Slippers Keep Your Feet Warm, Also Your House As It Burns To The Ground.

March 23, 2015 by 20 Comments

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.
