Racing shoes with curved carbon plates and lightweight resilient foam that improve running economy.
Advanced Footwear Technology describes a shoe construction that pairs a stiff embedded plate, usually carbon fibre, with a thick midsole of highly resilient, compliant foam such as PEBA. This combination underlies the 'super shoe' category now dominant in elite and recreational distance racing. The design is intended to improve running economy relative to traditional racing flats.
Patients and athletes will ask whether these shoes are safe, whether they should switch models close to a race, or whether a change in footwear explains a new ache. Because AFT changes loading and possibly running mechanics, it is a relevant variable when taking a history for lower-limb overuse presentations in runners, alongside training load and surface changes.
Running economy benefits are established through lab-based oxygen consumption or metabolic cost testing at fixed submaximal speeds, comparing AFT against control shoes, with average improvements around 2-4%. In clinic, application is mostly through history-taking: noting recent footwear changes, mileage in AFT versus other shoes, and any temporal link to symptom onset, since routine biomechanical assessment of plate stiffness or foam properties is not standard practice.
The 2-4% economy gain is a group average, and individual responses vary considerably by foot strike, body mass, and running speed, so it should not be presented as a guaranteed benefit for a given patient. Clinicians should avoid asserting that AFT definitively increases or decreases injury risk, since the mechanism of benefit and the long-term musculoskeletal effects of altered loading patterns are not yet well established in the evidence base.
