Also, check out Power Laces: Version 2.0



Why wait until 2015?

Inspired by 'Back to The Future II', this project is less 'Practical' than 'Proof of Concept', but hopefully it'll tide you over until Nike comes out with something more polished.

This was also the first time I worked with an Arduino microcontroller, and I wanted to get some experience with the little guy.

Operation is quite simple- step into the shoe and a force sensor reads the pressure of your foot and activates two servo motors, which apply tension to the laces, tightening the shoe. A touch switch reverses the servos.

Due to budget constraints, I only modified one shoe. Where did I put that darn sports almanac?!

And if you get a chance, vote for me in the Instructable USB contest!

Step 1: Parts & Tools


Parts:

A shoe  // a hightop with a lot of padding and undersole seemed easiest to work with and modify

Arduino  // I used the Duemilanove

Motor shield // The kit from adafruit.com works great, and allows control of multiple types of motors

Force sensor // Also got this from adafruit.com

Servo Motors  // again, also from adafruit.com.  Gotta save on that shipping whenever you can!

Sheet metal // about 4" x 4", enough to keep it's shape but easily trimmed with shears

LED and a couple of resistors  //  I only had  1K's laying around, so that's what I used

9 Volt case, with built in battery clip and switch

Insulated copper wire // I used high and medium gauge

Plastic zip ties, various sizes  // I went through a lot of these

Plastic 1/2" cable loops  // used for organizing cables

1/8" braided nylon paracord  // 10' should be enough


Tools:

Just the basics- soldering iron, screwdrivers, etc.  A hot glue gun is handy, too.

Misc:

A USB A to B cable and a computer to load the Sketch to the Arduino.

can you do a tutorial on version 2.0 and will it work with the shoe you used for version 1, & what shoe did you use for version 1?

Reese_Rules4 months ago

What force sensor did you use, can you be specific or send me a link

Reese_Rules4 months ago

Would these shoes be comfortable, if so if you could rate it 1-10 before and after the modifications.

thank you

Incredible. To make it more compact, use an Arduino Nano or similar model. (Ardweeny)
A teensy!!!
Are there more models for being able to pick your favourite colours?

Can you please help I can't find the Motor shield or the Servo Motors I looked at adafruit.com but no luck can you give me a link to them or tell me the names? Also where can I get the shoes
Servo motors can be found at any RC hobby shop. Pololu also carries servos.
i literally died laughing at the photo of the arduino and the airport caption you have quite the sense of humor haha
so...did you posses your computer?
yea my soul went into the computer and i'm processing like there's no tomorrow

Oh snap! Those are so cool. My brother loves Back to the Future, and I want to make these for him. I'll probably mess them up though and e-mail him this Instructable saying, "I tried." :-D Nice job!!!

mwayi3 years ago
its great to see such type of innovations it would really help the disabled i love that part as for children let them learn how tie shoes its part of exercise to bend their back and hands on the races.But is it not heavy now with all the gadgets behind it.By the way i really love the innovation part shows u are using ur brain wise i hope someday u will develop an amazing machine that will save this world.
all the best

Oh My Lord.
I almost cried when i saw the version 2.0 video
Where can i get these :')
see site title - instructables.  If you love it so much, why don't you marry it - err- I mean make it.
ohh.. is there one for the 2.0s ?
Actually, I didn't notice until afterwards, but he does want to market them: Back up to the top

GMer563 years ago
Not like the sports almanac would do much good. Its only for 1950-2000 :(
Does the motor keep constant pressure on the laces, or does it tighten them and just relax?
Either way, I think it could be simpler, but that is just me: Do things as cheap as possible and make sure it looks good.
Step 7:
Do I see the Ubuntu Matrix screen saver? :D
Great stuff, My son and I are making BTTF II next halloween and we have to make these.
Yes! The sound is great!

Why did you use a motorshield? Why not only a arduino?
arduino? NERD POWER!!?!?!?!?!?!?!?!
blakebevin (author)  roberthj3 years ago
So it would be bigger and clunkier.
Haha :), im just wondering, im a beginner. Are going to buy all these parts and when i showed this project for my teacher he was wondering why i needed a motorshield, not just drive the servo with the arduino.
Very nice idea and concept ^^ I hope to buy one of your shoes someday when they come out in stores!

This is off topic but you're very pretty :] (and i mean it in a friendly way) XD
Wow this is a great idea and very creative. I love the project and i support u and the shoes all the way. How old r u by the way. Contact me or just talk to me

macman8084 years ago
awesome instructable really cool, i have got the B.T.T.F triology and those shose look like the real thing. nice job and what style of shoe is that i know it's a nike but which one?
um no they dont uhh look again because they look nothing alike
ylpihs3 years ago
How long does the whole project take? Wanna do something similar to this as part of my Halloween costume. It will be so cool!
oh, just made a pledge on Kick Starter :) good luck with the development. James
WOW, love this. Was wondering if you would like some free sugru, thought it could help with your prototyping? :) Had seen this here a while back and just now on Kick Start, so so cool. Looking forward to this being a product. Hey, would you retro fit a customers trainers with the technology or sell a standard shoe with it fitted? Good luck. James
IM SO PUMPED FOR WHEN NIKE MAKES THIS!

wow thanks I still need to find all the money i need but thats AWESOME!
coppeis3 years ago
How do you put all the hardware in the shoe?
Best be careful! I just ran into this on the web, but you're in violation of a patent. www.engadget.com/2010/08/26/nike-files-patent-for-auto-lacing-sneakers-marty-mcfly-doth-pro/ They filed this in '09, so just be careful.
blakebevin (author)  drpepper84123 years ago
Hehe, this is a completely different mechanism than described in the patent. Plus I'm not selling it, so I think I'm safe. I am planning on raising some money though to create a better version, and the mechanism I have in mind will be different, more efficient, and more flexible. Competition is a good thing ;)
Most definitely agreed! Can't wait to see the finished product. Hit me up if you need an investor ;)

how much does the whole thing cost?
I just finishing making a pair, including buying a pair of nike dunks, and parts including shipping I paid $170
wow. lots of money
it was but the sneakers are pretty cool
you said that you could only make one because of budget... how much does making one cost?
170 says the mane on top....

could you use a lily pad arduino?
userhck4 years ago
Its interesting to note that in the actual movie they secured the shoes to a false floor of asphalt and someone just pulled the laces tight from below while michael j fox just set his feet in them.;
@blakebevin, have you tried the tv-b-gone from adafruit? I have been pondering it for awhile but before I buy my materials for this project I wanted your input. I think I will get it but wanted to know if you have built it.

As a person with disabilities I was thinking your invention would be great for para's, quads as well as elderly people. It is the seed of a great idea I think, just needs some refining. But anyway, congrats on winning. Great Instructable!

If you want to know how to make a million dollars with this.....hmmmmmmm...should I tell you ? Ok ...make a deal with the In-Line skates people to add this to their top of the line skates for 2 point on every one sold.

That's pretty awesome. Not only that, but today is also the day that Doc set the time to in Back to the Future.
backtothefuture.png
Nope. Internet hoax. The date was Oct 21, 2015. Now you know, and knowing's half the battle.
So that means we only have 5 years, 3 months, and 13 days to invent and implement flying cars, hover boards, and redesign the Pepsi bottle? We need to start working!
so when does work begin
GOOO JOE!
:(
False , in the movie the time set in the DeLorean always end with a 5 . watch the movie and stop spreading this lies .
shit, I never got my hover-board... where did we go wrong?

With a little more time and risk of wrecking shoes you could probably put the laces through the shoe and fix the motor in its own little pocket :P just for a visual effect. Great Instructable!

muscle wire threaded through some fibreglass heat resistant tubing could make for a simpler auto lacing shoe.
jmitc1114 years ago
hey are those black things up on the ankle part above and below the zip tye part of the shoe or the design

Part of the shoe.
phew i thought i missed part of the tutorial

what is the style of those Nike's...my girlfriend LOVES them!!!
blakebevin (author)  WyldStyl34 years ago
They say Nike Air, not sure about anything else. Got them from Ross.
this is amazing! the only thing i would do differently is i would make a small shell tho cover the electronics that matches the color of the shoe. maybe your next auto lacing shoe project could be water proof. =)
Steelsmith14 years ago
As a slightly disabled person who has problems tying his shoes: If l you develop this and can market this properly this could be a useful thing for paraplegics etc. It would need to look nice enough and be affordable, but some of us have problems tying our shoes.
metroid624 years ago
Those shoes are great! I need to try and make my own from your instructions, I just hope I don't need to go to the airport in them.

Azelis4 years ago
That is completely unnecessary, absolutely rediculous, totally useless, and I will be building my own as soon as I can afford the parts :-Þ I give this build a 'fully awesome' rating.
XenonJohn4 years ago
The tensioning system reminded me immediately of the Gibson Robot Self-tuning guitar. It has really neat compact servo operated device for tensioning each string (obviously you would not need that much tension else it would cut off your foot but you know what I mean). I agree it would be interesting for disabled people especially if the laces were low friction so the shoe sprung open automatically as the tension on the laces (or strap) was released, allowiing you to just step in and out easily. Would it be any advantage in ski boots or anything like that I wonder?
habzbah4 years ago
I want to make these, but does any one know how many inches the apparatus protrudes from the back of the shoe? I'm planning on making these and wearing them to Johnny Rockets :D Maybe I'll make a scene and start yelling that I'm from the future or something too.
noneedto4 years ago
this is a great idea!!!!! the only problem would be the circuits on the rear of the shoes.... i dont think they can stand alot of bumping. Water wouldnt be great either! i know it is just a design =D and i love being lazy!!! keep up your work! 5.0
hammer98764 years ago
Awesome!
brssnkl4 years ago
it is great but why did u worked so hard :D you could simply use one cord and a simple motor with a simple circut glue 2 magnets and 2 magnetic switch at the sides of shoes when u put shoes near the cords get simply opened or closed if u need a better explanation, contact with me :D
I like the idea it makes sense, could definitely be used to help the slightly disabled. brssnkl: I also think using magnets somehow would be a good idea if it works the same as his concept. But I don't understand your brief explanation. Maybe you can post a drawing of what you mean.
zeon4 years ago

Pablojr4 years ago
I think that you should have a loop on the side of the shoe for the lace to go through and hide that motor in the sole

switch624 years ago
Very, very cool.
What you have done is brilliant.

It wouldn't take much more work to take this from proof of concept to a practical application. You could certainly make the electronics smaller with a speciallized circuit.  That way it could fit in the heel or the ankle strap. The servos would need to be smaller. Have the straps run under the skin of the shoe.

How tightly do the laces hold ?  Are they as tight as normal laces ? 
beastyface4 years ago
hey dude i really like the shoes i will pay for a pair of the power laces my shoe size is a six and a half in nikes and if you can can yo sort of hide the motor
fluxuss4 years ago
if you can manage to use smd technology, I think it will be possible to hide all electronics into the bottom of shoe then it will be completley useful. I mean you can walk in the streets with this without looking like an android :D

The shoes were from Ross. The hat was from http://www.mirajcaps.com/ but they're sold out. Sometimes eBay will have the official Hat for sale.
Probably the coolest thing I've seen at anyplace, at anytime, ever. I foresee a steampunk version, but I dig the 80's look :)

Sweet, now if you can compact it down, maybe a worm gear to wrap the laces up or something. Also a side note I have that same red organizer on my work bench. Keep it up.

kirnex4 years ago
Not sure what to say. A lot of effort to be lazy. Otherwise, pretty damned cool! If any of us "lazy" people would ever get around to actually doing this...well, we WON'T. But...it's something for us to aspire to, anyhow (and add to our lists)!
oooh, awesome! 2015 comes early.
MK II could have SMD parts or even a flexible arduino and with some memory alloy actuator instead of servos, everything could be concealed in the sole and the tab so the shoe wouldn't look like there's an IED straped to it.


kcls4 years ago
You sure are a big fan of zip ties! Very cool 'ible. I can't see walking around in public with an arduino strapped to the back of my shoe :D. Maybe it would be fun! Couldn't board an airplane wearing them though...
laxap4 years ago
AFAIK, RC servos can be connected to the Arduino shield, directly: powered by VCC, and commanded by a PWM output. So my question is: why do you need the motor shield? Very cool project. I just love the BTTF trilogy!
blakebevin (author)  laxap4 years ago
I was originally gong to use DC motors, but it didn't work to well, so I switched to Servos. Figured I bought they motor shield and might as well use it ;)
nickodemus4 years ago
Smile, you're on Hackaday!
Okay, I'm impressed. Nice idea, and I bet someone could clean it up and integrate the whole device into the heel - especially in cross-trainers or similar shoes with a stiff heel. Nice job.
the future has come early
... and it looks like the 1980s :)

Last weekend someone introduced me to actual shoes that tighten a strap using a rotating knob on the front, a bit like the adjusters on some safety helmets. You could conceivably servo-power one of those for a tighter fastening- shoes for people with mobility problems, for instance?
