Aun no podemos afirmar si el calzado minimalista es una moda pasajera, o llegó para quedarse. Lo cierto es que prácticamente todas las grandes marcas ya cuentan con modelos y tecnologías en este rubro. Puma no se quedó atrás, y acaba de presentar las Mobium Elite.

Según sus fabricantes, el principal atributo de este calzado para running está en su capacidad de adaptarse al pie, expandiéndose y contrayéndose según la fase de la pisada.

Las Puma Mobium Elite están fabricadas para adaptarse a la elasticidad natural del pie, a partir de su suela exterior en forma de ocho. Los diseñadores de Puma se inspiraron en la máquina más eficiente de correr: el felino. Semejantes a las patas de éstos animales, el calzado tiene unos paneles externos llamados “Expansion Pods”, que se comprimen durante la fase de propulsión y se expande en el aterrizaje, para proporcionar una mayor amortiguación. Estos paneles trabajan en conjunto con una banda elástica integrada en la mediasuela bajo el arco que une talón y ante pie facilitando esa contracción y proporcionando más propulsión en el despegue.

Louis Joseph, Director de estrategias e innovación de Puma, asegura que esta tecnología es capaz de trabajar con la misma dinámica que los tendones del pie. A más fuerza aplicada, con más elasticidad responde.

Very limited-edition Viks bikes made from stainless steel and imagination

By Ben Coxworth March 26, 2013


The Viks is a stainless steel fixed-gear commuter bike, made in Estonia

If you create high-end carbon fiber bicycle frames and wheels for a living, what do you do when you’re looking for a fixed-gear commuter bike? Well, you don’t just get a Huffy. In the case of Indrek Narusk, designer with Estonia’s Velonia Bicycles, you create a stainless steel-tubed piece of art known as the Viks ... and then you start making them for other people, with an eye towards commercial production.

“I've always liked to have custom and different things you don't see on every corner,” Narusk told us. “So I thought about building a one-off custom frame. I did not want to build a regular diamond shape, so I started sketching different shapes and sizes. Some inspiration came from new school cafe racer-style motorcycles.”

When he thought about how the bike could actually be built, he realized that it would be easiest to form it from two tubular frames joined at the head tube, seat tube and bottom bracket. From there, he modeled the frame using SolidWorks, then set to work in his shop.

The first complete Viks bike he created weighed in at about 14 kilograms (31 lbs). He explained to us that he used overly-thick tubes, because they were all that was available at the time. Once other people saw his creation, however, they started asking about getting one for themselves. In response, he’s now pre-sold seven more Viks, which he’s in the process of building. Using thinner tubes and lighter components, he’s aiming at a weight of about 10 kg (22 lbs) for those models.


Like the somewhat similar-looking Rizoma, part of what gives the Viks its distinctive appearance is its lack of a seat tube. Narusk’s bike still accepts a standard 27.2mm seatpost, however, the height of which can be adjusted using a regular seat clamp.

For now, Indrek is waiting to see how thing go with his first seven bikes, and will set a price for any further bikes accordingly. “This wasn't intended to be a business project, rather a fun little side kick,” he said. “We'll see, if the interest continues to grow, then maybe I'll make some more, as building bikes is one of the best ways to spend time (besides riding them).”
