ON Cloudboom Echo 3 Review - First Impressions (FAST) - The FOD Runner

Aug 13, 2025

Intro: This is a quick summary of ON Cloudboom Echo 3 Review – First Impressions (FAST) from The FOD Runner. It’s a great watch — we’re breaking it down so you can try the workout today. Be sure to check out the full video for all the details.

Key Points:

The shoe was tested on a speed‑focused session: a 6‑minute tempo (~5:34 / mile), three 4‑minute intervals with 90‑second easy jogs, four 75‑second pickups, and a final 6‑minute tempo (the last two minutes uphill felt tough).
The Cloudboom Echo 3 features a 10 mm heel‑to‑toe drop, 37 mm heel stack, 27 mm forefoot stack, and weighs about 283 g (10 oz) in a UK 13.
Its Helion‑Hyper‑Foam mid‑sole delivers a responsive, bouncy feel without the “sinking” sensation, while a carbon speedboard and minimal cloud‑tech cut‑outs give a snappy transition.
Lacing with extra eyelets and silicone‑dot laces keeps the foot locked in, preventing heel slippage and ankle rub – a big win for long‑distance races.

Workout Example (adaptable to your own paces):

Warm‑up – 10‑15 min easy running.
Tempo 1 – 6 min at roughly 5:30 – 5:40 / mile (or your current threshold pace).
Intervals Set 1 – 3 × 4 min @ ~5:20 / mile with 90 sec easy jog recovery.
Pick‑ups Set – 4 × 75 sec fast effort (aim for ~4:30 / mile) with full recovery.
Tempo 2 – 6 min at threshold pace (same as step 2). Finish with a cool‑down. Tip: Adjust the paces based on your own recent race or recent threshold test. The structure lets you practice gear‑shifting and gauge shoe stability at speed.

Closing Note: Give the Cloudboom Echo 3 a spin on a similar speed‑day session and feel how the shoe handles your own paces. You can easily customize the intervals in the Pacing app to match your training zones. Have fun, and don’t forget to watch the full video for deeper tech insights!
