This is going to be just like in Back to the Future, part II, when the main character, Marty "Martin" McFly (played by actor Michael "J" Fox, now of the famous sitcom he stars in), wears some sneakers which light up and tie themselves, made by Nike [] .

One word: tight as hell.

The sneakers did not tie, they just sort of pulled one side to the other. Like some sort of automated zip tie.

Or like a self-tying suture? j/k, thx for the heads up.

I think that they did not "tie" themselves, rather just collapsed together, like an automated zip-tie

This is going to be just like in Back to the Future...

So they could combine that movie with "Doc Hollywood" where he wants to be a plastic surgeon in Hollywood and he can still drive a cool car, be a country doc and travel ahead in time to learn new surgical techniques and bring back new gadgets and they could call it "Back to the Suture: A Stitch in Time"

Now Mommy can retire. I don't need her to tie my shoes. I am wondering if they will make them in Plaid....

And thus an old and outdated practical joke gains new life: Shoes that tie themselves together

Self-tying shoes (2, Insightful)

!splut (512711) | more than 12 years ago | (#3418181)

Well, it'd be great if I had a pair of thermoplastic shoelaces that snugly knotted themselves for me. It wouldn't be so great if I needed a knife to get my shoes off. Can these things be untangled?

I've seen material like this years ago. They did it on Beyond 2000 or some show like that on the Discovery Channel. They showed how you can bend this material (they spelled a name) into a shape, then dip it in a chemical, straighten it out agian, and when you apply heat, it goes right back to how it was. (the order of events may be off, but thats basically how it went)

Cenam (567580) | more than 12 years ago | (#3419109)

this isn't really old news..this material can do more than just bend and straighten, it can move in more complex ways(like the knot if u would read the damned article), and it is don't with just a temp change, not applying seperate chemicals to diff parts..

Where was this when I needed it? (0, Troll)

gradbert (80505) | more than 12 years ago | (#3418746)

I sure could have used this stuff when I was taking sailing, we had to learn how to tie all sorts of knots. Here i was using my brains like an idiot, doing all of that hard memorization, when all i needed was a smarter rope

Hadlock (143607) | more than 12 years ago | (#3419375)

now when can i buy a (suit) tie that ties itself? :)

Didn't really tie itself did it. (3, Insightful)

mindstrm (20013) | more than 12 years ago | (#3422776)

All it did was tighten itself up.

They heat it up, it shrinks, and tightens the knot nicely.

Useful, but not exactly a self tying knot.
