Engineers, scientists, designers — above all, athletes.
Engineers, scientists, designers — above all, athletes.
Your watch can't see your feet.
Pace, heart rate and sleep are measured all day. How your feet actually hit the ground is not.
Measured underfoot, not at the waist or wrist.
Landing, foot roll and push-off, read by 128 sensors under each foot. A watch guesses these from your wrist.
Learns your baseline, then tells you when your form changes.
Your stride shifts as you tire, before you feel it. STRIV knows your normal, so it notices when a run starts to look different.
Left and right, tracked separately.
Most runners load one side more and never know. STRIV scores each foot on its own, so an imbalance shows up as a number.
Coaching while you run.
Ace watches your stride live and speaks up only when something is worth changing, so you fix it mid-run, not after.
Hardware: Lab-Grade Precision
Sits under the insole you already run in.
Peace of mind,
guaranteed.
We've got you covered, so you can focus on your run.
You run. STRIV tracks every step.
A complete picture of how each foot interacts with the ground throughout your run.
Hear from our early adopters.
Jake Riley, 2020 Olympic Marathoner & US Champion
“STRIV’s technology isn’t just another smart wearable; it’s a Game-Changer unlike anything I’ve seen before! After testing the sensors and reviewing the data firsthand, I’m convinced of its value!”
Joe McConkey, Head Coach @ Boston Running Center
“Accurate data with 128 sensors per foot, a very thin and unobtrusive insert and easy to understand results – STRIV is in position to become the industry leader in publicly available bio-mechanical devices.”
Dr. Drew Deppen, Coach, Chiropractor, Founder @ Motion Performance Group
“In a world full of gadgets that simply look sexy and take your attention, STRIV facilitates a more mindful way where one can see, in real time, if what they think is happening, is actually happening. It’s a Game Change for athletes, coaches, and clinicians.”
Keith Taylor, Ultramarathon Runner
“The number one benefit to STRIV is actionable insights while I'm running. If my form slips, I get that immediate notification and I can adjust. That's everything to me.”

Frequently asked
questions
A thin sensing layer sits beneath your shoe’s existing insole. Its 256 pressure sensors (128 per foot) and motion sensors map how load moves across both feet, every step, and stream the data to the app.
Watches and pods typically estimate pace, power, or other running metrics from the wrist or shoe. STRIV measures pressure and motion under both feet, then turns those patterns into live coaching cues and a clear post-run summary.
STRIV captures how pressure, force, timing, and movement change through every step. Explore the measurements on the Learn page.
STRIV’s measurements have been tested against Bertec force-plate treadmills, the gold standard for measuring running forces. See the validation on the Learn page.
Yes. Once your insoles are connected, STRIV captures every step automatically. When you choose live coaching, Ace can also surface cues you can act on during your run.
