Due to the nature of fractals, their edges are infinite in length, because you can always add another iteration.
Raised fractal patterns on the shoe would provide very good grip, due the infinite number of tiny gripping edges.
It would also leave very interesting footprints.

[Walabio]'s linky, cut'n pasted for your delectation [Dub, Jul 28 2009]

and when you took them off would this be called "a
fractical shoe loosen "? + |
|
| |
A pair of Mandelbrot brothel creepers for me. |
|
| |
Nice idea - but how long does it take to make the mould for the treads? |
|
| |
Love the idea, but [Dub]'s question is priceless. If only I could get my own engineers to think about design for manufacture... |
|
| |
"very good grip" - actually, per the gecko's foot, I think you'd have a hard time lifting your feet at all, as it would bond to the floor. |
|
| |
Good good stuff, [Dfox]. I wonder if an enormous fractal could be stamped in a huge rubber sheet, then soles cut from this. No two soles would be alike, though all would be similar. If there was someway to generate the fractal directly on the rubber (perhaps diffusing oil on the rubber, or a growing crystal) that would be a magnitude cooler. |
|
| |
would the gluey thing get less as it all got smaller? |
|
| |
Edit: Ahh, Idea title starting letters, I have every letter but K, Q, and X. Aha! |
|
| |
Big fractal, bounding through the snow! |
|
| |
"what can this foot print mean?" + |
|
| |
Not to be a spoilsport, but wouldn't the finer iterations wear away in minutes, leaving less and less fracticality every day? |
|
| |
it takes quite a bit of time to wear through an infinite tread. |
|
| |
A shoe print so unique, you could NOTARISE whatever you stepped on. |

Mandelbrot, the new Paisley for the trendy mathematician. |
|
| |
I've always wondered why fractals were said to be infinite in edge length. Has anyone proven that they don't converge to some finite number? |
|
| |
Would the infinite edge be infintely hard to clean when you stepped in finite doggy-doo? |
|
| |
Just spray it with an infinite amount of water! |
|
| |
Wouldn't the "infinite length" in this case be analagous to an infinite geometric sequence, in that it does converge to a number, but never actually reaches it? |
|
| |
Depending on which type of fractal you use, the change in edge-length varies. A good example is the sawtooth fractal, which doubles ever iteration. |
|
| |
Ahhh, remember Pratchett on 7-league boots, and their proper use? |
|
| |
I can see this working down several levels of fractility, but after about ten levels, wouldn't the texture of the rubber soles exceed the fractal pattern? + |
|
| |
Thank you, Sparty. Well asked. |
|
| |
It would of course. Fractals are only infinite in length conceptually and mathematically. As soon as you introduce them to the real world all that infinite stuff gets ignored by atoms and the like. |
|
| |
A friend once claimed that the M25 is a fractal, for although it encloses a finite area (Greater London), it takes a near infinite amount of time to traverse, and must therefore be infinitely long. |
|
| |
If you can create an infinite series in reality, please let me know. |

I stumbled upon this yesterday. I am 4 years late, but I have
some feedback: |
|
| |
At the time this idea appeared, Shoes For Crews: |
|
| |
http://ShoesForCrews.Com/ |
|
| |
Already had fractal treads. Shoes For Crews gloats that these
shoetreads reduces claims for slip-injuries in Workers’
Compensation by over half. |
|
| |
The good news is that fractal treads work. The bad news is that
someone else already patented it. The good news is that the
patent only covers a specific fractal pattern and that one can
create and patent a new fractal pattern for tire/shoe-treads. |
|
| |
Those shoes don't have fractal soles, nor do they remotely resemble
fractals in any way, which leads me to believe that new user [Walabio]
is just advertising for that company and should
have his/her comments removed – post-haste! |
|
| |
The soles seem to have largish squares each divided into four smaller squares, which hints at fractalness, kind of. |
|
| |
doubtful that a company shill would use the phrase "the company gloats that..." in a spam post. The word "fractal" doesn't appear on their website anywhere. |
|
| |
Intelligent spammification perhappenstance? |
|
| |
I like the idea but you'd have to make it from something that wouldn't lose its fractility within 50 yards of walking from abrasion. |
|
| |
¡I am not a spammer! I just stumbled upon this site and noted
that fractal soles already exists. Indeed I wear them. I work in
a
restaurant. The claims about slipresistance is on the website: |

If one looks at the pattern it is an obvious fractal. It is
selfsimilar on multiple scales. |
|
| |
It is true that the site never uses. The word fractal. I see 2
reasons it might not state that the design is fractal: |
|
| |
Perhaps a genetic algorithm created the pattern and the
company does not realize that it is a fractal. |
|
| |
I suspect the former because the company calls it SFC Mighty
Grip. SFC is an acronym for Space-Filling Curve. Space-filling
curves are a subset of fractals and the pattern on the sole is a
space-filling fractal curve: |

This all seems to boil down to confusing about what a fractal is: |

Many people are under the impression that fractals are always
chaotic. Many fractals are totally regular like the Sierpiński-
Triangle |
|
| |
http://tinyurl.com/m9gqvd |
|
| |
The only requirement for fractals is selfsimilarity. |
|
| |
The point is that for years, I wore shoes with fractal treads as
have millions. |
|
| |
Ever since I stumbled upon this page and decided to chimein, /i
thought about fractal treads and came up with mine own: |
|
| |
Start off with a right-angled isosceles triangles. The the groove
between the hypotenuse is 1 millimeter wide, 1 centimeter
deep and 1 decimeter long. The groove between the legs is the
squareroote of the hypotenuse in width, length. and depth.
Start cutting then in half with grooves the squareroot of the
legs. Iterate until the one makes hypotenuses less than 1
millimeter long. This should be near the limits of what one can
do with a mold. One should get great traction with that space-
filling fractal curve. |
