If The Shoe Doesn’t Fit, Print It!

August 4, 2023 by 15 Comments

Usually when we talk about flip-flops here we mean the circuit. But in this case, it is [Jeandre Groenewald’s] 3D-printed shoe design called Sloffies. The shoes use TPU, and the matching package prints in PLA. Of course, you have to pick the size to fit your feet, and there’s an OpenSCAD file that allows you to customize the strap.

Unlike some 3D apparel we’ve seen, these look like a commerical product. Of course, the cool product packaging doesn’t hurt any. Are they comfortable? We don’t know, but our guess is it is no worse than other similar shoes that are made of one material.

Hackaday Prize 2022: A Cooler For Your Footwear

September 2, 2022 by 15 Comments

Sweaty feet can be uncomfortable, and the smell generated in one’s shoes isn’t much to admire, either. In an effort to help solve this issue, [Revoxdyna] has created a cooler for one’s feet that should help out in hot conditions.

Modern shoes, particularly sneakers, are often ventilated, but it’s not always enough. This build takes things further, using active cooling. Water is pumped through tubes and into a copper insole which cools the sole of the foot. It’s achieved thanks to a pump assembly that mounts to the rear of the shoe in a 3D printed housing. The water itself is chilled with a thermoelectric cooler, which helps remove heat from the shoe area.

There is some bulk to the design, which would prevent its use in performance applications in its current form. However, we could imagine companies like Nike leaping at the chance to build some very fancy, high-tech shoes along these lines in future. After all, they already managed to create power laces, and this is even cooler again! Pun definitely intended.

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

March 3, 2022 by 14 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.

Dry Your Boots With The Internet Of Things

June 24, 2019 by 16 Comments

If you live somewhere cold, where the rain, snow and slush don’t abate for weeks at a time, you’ve probably dealt with wet boots. On top of the obvious discomfort, this can lead to problems with mold and cause blisters during extended wear. For this reason, boot dryers exist. [mark] had a MaxxDry model that had a timer, but it wasn’t quite working the way he desired. Naturally, it was begging to be hooked up to the Internet of Things.

The brains of the dryer is an ESP32, a solid choice for such a project. With WiFi on board, connecting the device to the internet is a snap. Relays are used to control the fan and heater inside the boot dryer, while MQTT helps make the device controllable remotely. It can be manually switched on and off, or controlled to always switch on at a certain time of the day.

It’s a simple project that shows how easily a device can be Internet controlled with modern hardware. For the price of a cheap devboard and a couple of relays, [mark] now has a more functional dryer, and toasty feet to boot.

We don’t see a lot of boot hacks here, but this magnet-equipped footwear is quite impressive.
