The sensor is easy to attach, but placement matters. Follow these steps:
Pick your leg
If you’ve had injuries, place the sensor on the leg with the most history.
No injuries? Great — choose either leg, but stick with the same one for consistency.
Strap it to your leg
Place the strap (with sensor + mount) about 10 cm above your inner ankle, on the flat part of your shin bone.
Attach the sensor to the mount
Press the pins of the sensor firmly into the mount.
Make sure the sensor faces slightly inward.
The logo and text should be upright and readable — that’s how you know it’s in the correct position.
Adjust for comfort
Tighten the strap so it stays in place, but keep it comfortable and non-restrictive.Do a quick test
Before starting your run, jump a few times or jog in place for a few seconds to check if the strap stays secure.
ℹ️ It's possible that you, while running, "kick" the sensor out of the mount. The best way to prevent this is to put your socks over the sensor.
✅ You look great! Your sensor is ready and so are you. Let’s go for a run!
