Puma released the FAST-RB NITRO Elite 2, a road running shoe with two fused carbon-fibre plates and a 55mm heel stack, in limited quantities on October 28, 2026, for £310. [T3](https://www.t3.com/active/running/puma-fast-rb-nitro-elite-2-1126) reported the launch, which puts the shoe above World Athletics' 40mm sole-thickness limit for competitive road racing.

## How the FAST-RB NITRO Elite 2 Is Built

The [Puma](https://akta.pro/company-profiles/0002e7x/puma) shoe carries two fused carbon-fibre PWRPLATES that form a springboard structure beneath the foot, an approach T3 describes as different from the single-plate designs used in Nike's Alphafly and most other supershoes. Puma has also revised its NITROFOAM ELITE cushioning, pairing a softer inner core with a firmer surrounding layer to improve energy return.

The redesigned ULTRAWEAVE upper is intended to be lighter and more breathable, and a PUMAGRIP outsole provides road traction. The heel stack measures 55mm and the forefoot stack 47mm, both above the 40mm limit that applies to competitive road racing. Puma developed the shoe over two years, and its internal lab testing indicates it delivers greater running economy than any other road running shoe in its current line-up, along with the highest energy return the brand has recorded in testing.

A UK size 8 weighs 250g, which T3 notes is not exceptionally light by modern supershoe standards given the size of the sole. Puma estimates a lifespan of around 320km (200 miles). The shoe is available from Puma UK, and the company's [own product pages](http://us.puma.com) list its running range.

## Puma's NITRO Platform Across Categories

According to akta.pro [company records](https://akta.pro/company-data), Puma opened the PUMA NITRO Lab in Los Angeles in June 2026 and launched the Ultra NITRO 7 football boot at 180g, the first use of NITRO foam technology in football footwear. The same records list Puma as the original and title partner of HYROX, the standardized global fitness competition format, and as AC Milan's official kit supplier.
