Puma Fast-RB Nitro Elite White Yellow Purple Collector Running Shoe

RB stands for Rule Breaker, and this is the most extreme running shoe Puma has ever made. Yellow and purple blocks across a white laceless upper make it the busiest colorway of the release, and the one that best reveals the three-plate midsole build.

Why collectors want it

It sits 18 mm over what World Athletics allows, so it will never toe a sanctioned start line. Instead it offers long road runs on a platform nothing else can match, plus a strictly limited production run.

• 58 mm NITROFOAM Elite heel: 46 mm at the forefoot, 12 mm drop.
• Three PWRPLATEs: full-length carbon combined with two TPU plates up front.
• No laces, no tongue: a mesh upper held by PUMA PWRTAPE.
• PUMAGRIP outsole: borrowed from Puma's racing line.
• Limited: 1,000 pairs worldwide.

Fit & sizing

Road only and not legal for competition. Offered in EU 36 to 47, shipped free with tracking.

Most performance running shoes are built on a single unisex last: the shoe is identical, only the size label changes. A US women's 8.5 is a US men's 7.

Use the unit switch above to move between US men's, US women's, EU and UK, or open the size guide for the full conversion chart.
