Fast-R Nitro Elite 3

Great for a 5K PR; handles slow paces but wants good form.

“I've only used them for a 5k PR thus far. They were great for that.”

Loves it but can't use it beyond 5K due to heel instability.

“Love the r3 but cannot use for more than a 5k due to the heel stability”

Worked for a 3:24 marathon but felt unstable and gave hip-flexor niggles.

“I'm \~85kg and used the Fast R N Elite 3 for a 3h24 marathon this year. I had some niggles on my hip flexor during the longest long runs.”

Extremely fast but painful past half distance and hard to hold form late.

“best way to describe it was not fun but fast. Every time I laced up the Fast-R 3's for a half and above, they've felt painful on the legs + feet but extremely fast.”

130 race miles across three marathons at 190 lb with PRs and no injuries.

“I have about 130 miles across races on my Fast-R Nitro Elite 3s and they've performed well in all races.”

A 4-minute marathon PR over the Alphafly and better late-race form, but calves cramped at the end.

“I ran 2:53 in May of 2025 in Alphafly and 2:49 in December 2025 in Fast-R 3. The Fast-R holds your form better in the back half”

Uncomfortable by 28 km of a long run; loves it for shorter races.

“I used the Fast R3 for a 32k long run, they got real uncomfortable around 28.”

Faster than their Vaporfly 4 in a side-by-side 400 m session.

“The first time out with the Pumas I ran 10x400, with the first five wearing the Nikes, then switched to the Pumas for the last five. The Pumas are fast.”

Faster than their Alphafly 3 and carried them to a 2:45 marathon, though it tore up their calves.

“was thinking they were faster than my Alphafly 3 but less comfortable. Went with pumas. Torn up my calves but didn’t damage my feet at all and helped me run 2:45.”

After 165 miles: lightest shoe they own and their go-to workout shoe, still like new, though tough on the balls of the feet.

“they've now become my go-to shoe for midweek workouts this training block.”
