Oh, patents! Balenciaga Race Runner Sneaker

The Race Runner Sneaker is brought to you by the century-old, Spanish Basque, luxury fashion and shoe design company, Balenciaga.

The Race Runnier Sneaker is patented. The US design patent USD737552 titled Sneaker was awarded to the Isabelle Guichot, the recently exiting Balenciaga CEO.

Just as a reminder, the difference between a US design patent and a US utility patent is the following:

“a “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171)” (USPTO)

Figure 1, on file for the US patented design, is included with an image of the marketed product, called the Balenciaga Road Runner Sneaker.

Oh, patents! Adidas Springblade™ shoes

For runners, sole cushioning is synonymous of running free of repetitive stress injury. And every running shoe manufacturer has their own patented system for cushioning the soles of their running shoe products, whether it is foam, encapsulated air, shock-absorbers like those of automobiles, or special toe and heel reinforcement pads.

The Adidas shoe designers have invented the Springblade™ to remedy some of the disadvantages of foam cushioning. They point out that the dynamic properties of foam are strongly weather-dependent, that is, foam hardens in cold weather, which is exactly the opposite of the desired cushioning effect. They also point out that foam wears out under repetitive compression and shearing loads, and every runner knows how to check the soles of their running shoes for signs of flattened and wrinkled foam. Finally, they also point out that the manufacture of foam soles cannot readily adapt to the weight of the user, or the shoe size, at reasonable cost, which results in both varying hardness of the soles and varying wear.

The Springblade™ system, with its spring leaves engineered out of temperature independent and long life material, also adaptable to shoe size and easily manufactured, thus arises both as an alternative to foam and as remedy for its disadvantages.

Below, you will find the abstract of patent US2011138652, titled Shoe and Sole with one of the patent drawings, and two images of the marketed product, the Adidas SpringBlade™ shoe. The blue shoe is the Men’s version and the Pink one is the Women’s version!...
