After testing it on elite runners and real athletes, we digitally engineered and optimized the product fully based on data. Fast-R3 is designed to shave minutes off your race time. With its 3.15% improved running economy*, this translates to an unprecedented potential marathon time saving of more than 4 minutes and 30 seconds, for a 3 hour marathon runner. We cut 95g from its predecessor, stacked it higher with new and improved NITROFOAM™ ELITE, and extended the carbon PWRPLATE for maximum propulsion. *Compared to the PUMA Fast-R NITRO™ Elite 2\u003c\/span\u003e\u003c\/p\u003e","brand":"Puma","offers":[{"title":"Heat Fire\/ PUMA Black \/ 7","offer_id":54346750296367,"sku":"312061 03 - 7","price":299.95,"currency_code":"USD","in_stock":true},{"title":"Heat Fire\/ PUMA Black \/ 7.5","offer_id":54346750329135,"sku":"312061 03 - 7.5","price":299.95,"currency_code":"USD","in_stock":true},{"title":"Apple Spritz\/ Deep Plum \/ 8","offer_id":54346750591279,"sku":"312061 06 - 8","price":299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5803\/0639\/files\/Screenshot_2026-02-26_at_3.25.35_PM.png?v=1772141207","url":"https:\/\/runners-republic.com\/products\/womens-puma-fast-r-nitro%e2%84%a2-elite-3","provider":"Runner's Republic","version":"1.0","type":"link"}
