Pumoma says she has made the fastest operating shoe ever. We put it in the test

Weight saving is a top priority, too. Studies show This is for every 100 grams (about 3.5 ounces) shaving your shoes, the running economy improves by about 1 percent. Fishing is always running for lighter foams, ways to cut unnecessary materials from the middle sole, plate and outer sole. The abstract upper parts also play a role with the minimum heel holes, thin tongues, and hard-network.

Whether you are targeting the marathon race without 3 or 5 hours, the temptation of promised performance gains is strong. However, the effectiveness of carbon shoes varies greatly from shoes to shoes, and hostility to hostility.

The research indicates While some contestants face improvements in the economy through new shoe technology, others see the minimum benefits or even a decrease in performance. Individual vital mechanics, running speed and adaptation with shoe design play an important role. The key is to find the shoe you respond to.

Mixed results mean that we have not seen any competitive claims competing with the original Nike seal by 4 %. yet.

The new Fast-R Nitro Elite 3 says does not open the gains of efficiency that exceeds any other shoes on the shelves at the present time. But it is also an operating shoe everyone The contestants respond.

Try and test

She sticks to the classic high -quality shoe recipe: high -quality foam is right in nitrogen, a full -length carbon plate, incredibly lightweight luxury and a very thin layer of external rubber. But in some respects, it cuts a unique shape with a separate Midsole sole, and a very slope that provides weight and the extended carbon plate that pretends to the front to obtain an additional lever.

Changes from Puma Fast-R2 to Fast-R3 hidden, but Puma promises to make a difference. Zero requires the details that opened the improved efficiency, a new design approach inspired by digital models in Formula 1. Nowadays, adjustments are often designed on F1 cars, not physically on the track. PUMA mainly applied the digital modeling approach similar to the development of running shoes.

“We have recorded 3D a 15 athlete, then we used a computer to reduce them and convert them into one,” says Todd Falker, the lead of products in Puma. “We can then take this digital strike and monitor how all the contestants have interacted with the digital shoe.”

Roman Gerrard, Vice President of Innovation in Puma adds more. “We repeated the behavior of hostility in a three -dimensional world, but the symmetrical copies are 100 percent accurate. The way the shoe actually behaves is the same in computer simulation.”

The technology not only allowed designers to determine parts of the shoe that has not been used, for example 5.2 percent of the size of the middle sole foam had no effect. So it was cut. But it enabled the designers of the 100s “test” of the different exchange of design without having to have a long process of creating many physical models for re -testing on the contestants.

“You usually need to create one plate, a second plate, and a third plate, then test it,” says Gerard. “But we were able to test hundreds of paintings and formations digitally until we had a better couple, and then we had to make a decision.”
