In September of 2014, the Kenyan marathon runner Dennis Kimetto set a record 2:02:57 marathon time in Berlin while wearing adizero Adios BOOST sneakers. More than just being a stunning achievement of athleticism, it helped cement adidas’ then new BOOST midsole as legitimate running technology. Now, nearly four years later, the brand is getting ready to release an improved BOOST mid in a shoe that they hope breaks the 2-hour marathon time; the adidas adizero Sub2.
The latest salvo in the arms-race (or foot race?) to set a world-record marathon time, these new runners feature a number of updates specifically designed to make them as fast as possible. The upper, for instance, is made from a special ‘reduced-weight’ mesh that is much lighter and more breathable than even Primeknit. But adidas’ put more than just the upper on a diet. They also reduced the weight on the BOOST midsole, dubbing it quite simply ‘BOOST Light’. To round the whole thing out, the shoes also feature a grippy, tough Microweb outsole from Continental. These sneakers – initially only available to professional athletes – will be released to the public starting March 15th and will retail fort $180.
